Commit 2804afc606f8 ("kms_frontbuffer_tracking: fix compression
checking") removes the check whether the kernel supports reporting the
compression status before asserting on it. This breaks the test for no
good reason on old CPUs (SNB and earlier) where the kernel can't report
the compression status. Instead, we can check if the cpu doesn't
support reporting and adopt the same behavior as if
--no-fbc-compression-check was used.
