gnu: python: Make the build reproducible.
While Python build was reproducible on a single machine, once multiple file
systems entered the picture, it was no longer true.  The solution adopted by
the upstream (and Debian) was cherry-picked.

More info: <https://github.com/python/cpython/pull/8226>.

* gnu/packages/python.scm (python-3.10) [source]: Apply reproducibility patch.
