[PATCH v3 5/5] docker-compose: Massively simplify

[Stephen Finucane]

Now that we can run tox on the localhost, we no longer need to install
the variety of Python versions we previously did and can keep this
purely for the 'manage.py' use cases.

Signed-off-by: Stephen Finucane <stephen at that.guru>

v3:
- Re-add the 'build-essential' package to the install, as that was
  necessary
- Stop installing 'virtualenv' and 'tox'
- Remove unrelated changes to 'tox.ini'
