Bug #834772: Unit tests fail on Python 2.6

On Python 2.6 (and below) load the unittest2 module, and alias it to unittest.
This brings in the assertIn function (among others) which is now used by
some unit tests, but isn't available on Python 2.6.

install_venv.py has been updated to add unittest2 as a dependency on
Python 2.6 and below, using a separate pip-requires-2.6 file that extends
the default one.
