Jesse Pretorius df9f5bc212 Fix problem with ARA execution for tox envs not named 'functional'
The ARA prep currently hard codes the tox environment name to
find pip/python in the tox env called 'functional', which does
not universally work.

This patch removes the strict path for pip/python as the script
only runs once the python venv has been activated and therefore
the correct binary path is used.
