pythonPackages.limits: hack around versioneer non-reproducibility
Context: #84312 documents that using .gitattributes on GitHub results in
non-reproducible release tarballs. versioneer uses this to provide
version numbers for Python libraries.

Hack around that issue by deleting the file containing substitutions in
the fixed hash input derivation, and recreate the required info from the
derivation's version info at patchPhase time.
