These tests require DRM master right, so make sure they have it from the
beginning. This gives an early indication if another DRM master is running
and makes the given test skip (with a proper explanation of the reason)
instead of exiting with error.

kms_flip_event_leak will issue a page flip and close the file
descriptor before the flip has finished. This may cause the kernel
to leak the page flip event. The test itself won't actually fail but
if the kernel notices the leak and WARNs piglit will report a failure.
