gst-env.py does not set GST_PLUGIN_PATH

[Nirbheek Chauhan]

Hi Jim,

This shouldn't be happening, could you please file an issue about this
at: https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/new

Can you try doing:

./gst-env.py --only-environment > all_env.sh
. all_env.sh

And see if that sets GST_PLUGIN_PATH? Does the set value match the
value in all_env.sh?

Once we've figured out the issue, we can either fix the issue itself,
or work around it by relying on the plugin loader's recursive nature
and only adding top-level directories.

Cheers,
Nirbheek
