MAR-132: Workarounds for wsgi_website Python virtual environment in Debian Stretch:

- Manually install setuptools in Python virtual environment on Debian
Stretch, otherwise the pkg-resources==0.0.0 package will mess with
pip freeze etc.
- Add back installation of futures package, even on Python 3 (since it
does not cause any harm).
- A small cleanup of how requirements are treated will be done in
separate ticket.
