We're studying the possibility to implement a Kernel FBC workaround
that will deactivate FBC every time the FBC frontbuffer was ever
CPU/WC mmapped. Due to this, we can't just reuse our FBs between
tests: the test suite will eventually CPU mmap every buffer, so FBC
will be disabled forever. In order to avoid this, keep it simple and
just recreate the FBs at every subtest.
