Reprotest fails to run correctly due to files that are not marked
executable:

The reprotest version 0.7.21 included in guix v1.4.0 did have these
files marked executable, but for some reason in recent versions (maybe
changes in pyproject-build-system?), they are shipped without the
execute bit set. I have not git bisected between all the versions of
guix to see exactly where it starts failing.

CCed members of the python team if they have ideas about changes in the
build system which might cause the issue.

The attached patch marks the necessary files are executable with an
added phase. Open to refactorring the patch, but my guile skills are
quite limited and this works!
