File transmageddon-appdata-prjgroup.patch of Package transmageddon

Change the project_group field from GStreamer to GNOME

GStreamer is currently not a valid group and appstream-util validate
chokes on it, declaring the repositories appstream where transmageddon
lives in, as invalid.

This only impact 3rd party repos (not the Distribution itself).
The distribution (openSUSE Tumbleweed and Leap) make use of appstream-builder
to produce a valid appstream metafile. as-builder happens to substitute
GStreamer as well for GNOME, based on the findings in the .desktop file that
the entire infrastructure used is GNOME.
