Is this test redundant with the test from patch 6? It seems like both
tests operate by creating a framebuffer and then checking that
TEST_FRAMEBUFFER_ATTACHMENT_LAYERED returns the correct result.
There seems to be a fair amount of duplicate code between the patches in
this series, so it seems like it might be nice to merge these two tests
into one if it's possible to do so without losing anything of value.
