If there' is a gap in testing in kms_frontbuffer_tracking compared to
kms_fbc_crc then I think we should fill that. I'm doing just that to be
able to remove another almost-duplicated testcase. But having testcases
around just in case is imo not that good, since they do eat machine time
we don't really have a lot of, and they eat maintenance time too.

Thanks for your acks, patch applied.
