Currently PYTHONPATH is hardcoded and assumption about
python version is made. While its recommended to use systemd,
we still can fix circus by retrieving venv lib path.
As a package location we pick gunicorn as smth we expect to
be present anyway. As a result we will get
{{ lib_path }}/gunicorn/init.py so we apply dirname twice to get
just lib_path that can be re-used later on
