We now use a different approach to setting up our uninstalled python environment: We add the gst-python folder to PYTHONPATH, and it no longer contains __init__.py files. This means that import gi.overrides correctly loads pygobject's __init__ module, but import gi.overrides.Gst also works, as __init__ files are no longer required by python.
