gstreamer1.0-plugins-bad/ugly: use the GPL-2.0-or-later only when it is in use

Since all gstreamer modules uses LGPLv2.1 with exceptions
for some plugins in bad and ugly modules that has GPLv2+.

For the GPLv2+ this patch set this license only for each plugin
that is affected by by that, using the new GSTREAMER_GPL.
