dev-python/gst-python: Restrict for pygobject-3.52 compability

Moves to revision 1 and introduces:
  - A <dev-python/pygobject-3.52 restriction for versions lower than 1.24.11-r1
  - A dev-python/pygobject-3.52.3 compability patch for version 1.24.11-r1

Note that the move to revision 1 was done in a separate commit for
gst-python-1.22.11 to avoid git emitting a misleading diff.

+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
