Changelog-None: `towire_wireaddr()` and `fromwire_wireaddr()` in `common/wireaddr.h` are responsible for marshalling/unmarshalling BOLT #7 address descriptors. Since these aren't tested by the existing wire fuzz tests, add a roundtrip test for them. This has the added benefit of testing `parse_wireaddr()` as well.
