Arnout Engelen 17c840055e setuptools: stable file ordering for sdist
We already re-pack the source distribution to make the
timestamps consistent, but the result is still not
entirely stable because by default tar does not sort
the files in the archive deterministically. This PR
makes sure the entries are sorted by name.
