it is time to investigate upgrading to python 3.10 in the win and mac binaries

debian 10 only distributes libxcb-util0.
debian 11 distributes libxcb-util1.
our base image atm is debian 10, so we build the package from source.
Change Docker base images from Ubuntu to Debian, and use `snapshot.debian.org` as apt source list.
Ubuntu occasionally removes version-pinned packages from apt (see #7484), which
- breaks historical reproducible builds
- introduces maintenance burden as we have to update the version pins
Hopefully this change fixes both issues.

This reverts commit 0c2a885c66.
Reverting for now due to reproducibility issues:
```
error: /Users/vagrant/Downloads/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate: can't open file: /tmp/electrum_compare_dmg/signed_app/Electrum.app/Contents/MacOS/libffi.8.dylib (No such file or directory)
```
`Electrum.app/Contents/MacOS/libffi.8.dylib` is included when building on one machine, but missing on the other...
Will have to investigate later.

We now distribute two tarballs, a "normal" one (the default, recommended for users),
and a new strictly source-only one (for Linux distro packagers).
The normal tarball, in addition to including everything from
the source-only one, also includes:
- compiled (`.mo`) locale files (in addition to source `.po` locale files)
- compiled (`_pb2.py`) protobuf files (in addition to source `.proto` files)
- the `packages/` folder containing source-only pure-python runtime dependencies

4.1.5->4.2.1, the appimage grew 54M->66M. This change shrinks it back to 58M.

We should delete `usr/lib/python3.9/config-3.9-x86_64-linux-gnu/` (which is 33M unpacked)
With py3.7 (electrum 4.1.5), this folder was named `config-3.7m-x86_64-linux-gnu`,
presumably because the default config to compile py3.7 was `--with-pymalloc`,
but maybe it is not for py3.9... ? not sure. (see https://peps.python.org/pep-3149/ )
This is bumping the python versions bundled inside our binaries.
For macOS and AppImage, from 3.9.10 to 3.9.11.
For Android, from 3.8.12 to 3.8.13.
Windows is left untouched as I am having issues with the wine build when using 3.9.11.
(see https://github.com/spesmilo/electrum/pull/7721#issuecomment-1071901116 )
This includes two logically separate changes:
- on the host, try not to require sudo when running the build scripts
- namely when interacting with the docker daemon, this requires
the unix user on the host to be part of the `docker` group
- this solves part of https://github.com/spesmilo/electrum/issues/7602
- while running inside the docker containers, do not run as root
- this means that e.g. files created in mounted folders should
no longer be owned by root on the host
- there is some code duplication involved here - not sure
how it could be deduped.
maybe fixes https://github.com/spesmilo/electrum/issues/7640
Looks like by default pip is ignoring the locally available setuptools and wheel,
and downloading the latest ones from the internet at build time...
https://pip.pypa.io/en/stable/reference/build-system/pyproject-toml/?highlight=no-build-isolation#disabling-build-isolationhttps://stackoverflow.com/a/62889268
> When making build requirements available, pip does so in an isolated environment. That is, pip does not install those requirements into the user’s site-packages, but rather installs them in a temporary directory which it adds to the user’s sys.path for the duration of the build. This ensures that build requirements are handled independently of the user’s runtime environment. For example, a project that needs a recent version of setuptools to build can still be installed, even if the user has an older version installed (and without silently replacing that version).
>
> In certain cases, projects (or redistributors) may have workflows that explicitly manage the build environment. For such workflows, build isolation can be problematic. If this is the case, pip provides a --no-build-isolation flag to disable build isolation. Users supplying this flag are responsible for ensuring the build environment is managed appropriately (including ensuring that all required build dependencies are installed).
If only it were that easy!
If we add the "--no-build-isolation" flag, it becomes our responsibility to install *all* build time deps,
hence we now have "requirements-build-makepackages.txt".
The latest release of appimagetool bundles a new enough version of
mksquashfs. We had been building a fork of mksquashfs but all the
relevant patches there had been upstreamed.
Note: we still need a wrapper when calling mksquashfs, as appimagetool
calls it with "-mkfs-time 0" and we have the SOURCE_DATE_EPOCH env var
set; and these two would conflict.
Two ways to fix: either unset SOURCE_DATE_EPOCH for that context, or
build a wrapper that removes the "-mkfs-time 0". The former would be
cleaner but for some reason I did not manage to build reproducibly
that way. The latter seems to work.
