[bug#68407] [PATCH python-team v2] gnu: python: Make the build reproducible.

[Tomas Volf]

While python build was reproducible on a single machine, once multiple
file systems entered the picture, it was no longer true.  My local builds on
BTRFS differed from build on ext4 done in a virtual machine.

The solution adopted by the upstream (and debian) was cherry-picked.  With
this patch, build on my machine (BTRFS) and in a guix system vm (ext4) produce
the same store item.

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

Use patch directly from the upstream.
