Robert Mader c83f0a1539 tests: Add test for subsurfaces mapping hierachies
Test different scenarios where child subsurfaces of unmapped
subsurfaces would get mapped. This test will fail in various
ways without the commit
"libweston/compositor: Do not map subsurfaces without buffer"

Also try to test potential regressions of that patch.
