Fix nox job python2.7 support

Browse Source 
Virtualenv dropped python2.7 support. When we install latest nox it also
installs latest virtualenv. Then when we try to run python2.7 jobs which
will create a python2.7 venv things fail with:

  RuntimeError: failed to find interpreter for Builtin discover of python_spec='python2.7'

The underlying issue is that we are getting a too new virtualenv. Fix
this by adding a pre run step to the python2.7 jobs that downgrades to a
version of virtualenv that should support python2.7 environments.
