Building python-gst fails with:

  Unbound variable: python-version

Therefore, add python-build-system to #:modules so that it's imported, and
give it a prefix to avoid clashing with the gnu-build-system.

Also, simplify the code by using the site-packages function from the
python-build-system module.

failure.
