python3: add supported python versions to setup.py
Mercurial technically can support Python 3.5 (although no lower, see its
setup.py), but `evolve` probably won't because it represents more work
for an underrepresented Python version. If you happen to *really* need
evolve to work on Python 3 and you're reading this message, send an email
to the mailing list, or contribute patches.
