RFR: 8284437: Building from different users/workspace is not always deterministic [v2]

[Andrew Leonard]

> This PR fixes the non-deterministic behavior when building on linux with different userids or within
> different workspace folders.
> It fixes the following issues:
> - MakeZipReproducible.java used to produce reproducible src.zip removes the optional zip "extra" field containing UID/GID.
> - When absolute output paths are not allowed, enable the use of -fdebug-prefix-map to ensure debug symbol info does not contain the top level workspace folder.
> - For reproducible builds ensure the gcc random symbol name generator is seeded using -frandom-seed.
> - For reproducible builds when producing debug symbols use relative object paths for library linking to remove absolute MASM object paths.
