Subject: [PATCH] configure: define macro for fuzzing builds

Sometimes we want to disable certain functionality or otherwise modify
code for fuzzing. The FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION macro is
a standard way to accomplish this.

See https://llvm.org/docs/LibFuzzer.html#fuzzer-friendly-build-mode.
