Also check site_packages when checking virtualenv

When we uprev Python, the new Python virtualenv will use a different
site-packages directory which includes the version in its name.
Adding a check for site-packages here will make create_venv
automagically uprev and reinstall the virtualenv.

This has enough potential to save much headache down the road and the
change is small enough to be worth doing now while Im thinking about
it.
