tests: Add a check for the new compositor pad-is-obscured optimization
We verify that all the buffers on an obscured sinkpad are skipped by overriding the map() function in the GstVideoMeta of the buffers to set a variable when called. We also test that the buffers do get mapped when they're not obscured. Blame^WCredit for the GstVideoMeta map() idea goes to Tim. https://bugzilla.gnome.org/show_bug.cgi?id=746147
