Subject: [PATCH] gst-python: fix compatibility with PyGObject>=3.52.0

PyGObject 3.52.0 moved OverridesProxyModule _introspection_module to __slots__,
causing Segmentation Faults when accessing the field.
Since _introspection_module is used to get Gst.Element but is never actually
used afterward, we fix the issue by removing this part.

Fixes #4314
