update tests to use the packaged version of the scripts

The tests were always running the local source copy of
virtualenvwrapper.sh, which does not ensure we are packaging and
installing that file properly. This commit changes the logic for
loading the wrappers so when the job is running under tox we always
look in the virtualenv's bin directory.
