Disable tests that require working mutter & xwayland

These extra build tests were only enabled starting in July when I noticed they were hidden in an old merge request we hadn't reviewed !7 (closed) . Therefore, since we've gone years without them and because we do test these features as we naturally use GNOME, perhaps skipping all these tests is ok.
These tests require working Mutter and now xwayland even though gnome-settings-daemon itself is a component of several other desktops that do not use Mutter. The tests were working ok with 46, but began frequently failing with 47~rc when they were switched to xwayland.
Alternatively, we could selectively disable tests. Since these particular tests are in Python, we could use @unittest.skip. The most common failure is with the xsettings test.
