gstreamer1.0: update 1.20.5 -> 1.22.0

Drop xingmux license snippet from plugins-ugly as it moved to plugins-good;
the license was LGPL in any case:
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/blob/d132592423be64ec18a223b67810ac89f391277e/subprojects/gst-plugins-good/tests/check/elements/xingmux.c

videoconvert/videoscale plgins were merged into one.

-Subject: [PATCH] bin: Fix race conditions in tests
-
-The latency messages are non-deterministic and can arrive before/after
-async-done or during state-changes as they are posted by e.g. sinks from
-their streaming thread but bins are finishing asynchronous state changes
-from a secondary helper thread.
-
-To solve this, expect latency messages at any time and assert that we
-receive one at some point during the test.
