Reclaim the python3-libraries fuzzer (repo change)

https://github.com/guidovranken/python-library-fuzzers has been deleted for the
owners own reasons.  We've restored a fork of that repo and would like to keep
this fuzzing running for the CPython project.

TBD - we may put a clone under the /python/ org on github instead of within
a fellow core devs personal github.  If so I'll make another commit before
proceeding with a PR.
