[PATCH i-g-t v3] tests/kms_atomic_transition: Skip blocking transitions on MTK

MTK blocking atomic transition commits do not satisfy the
immediate page-flip event or out-fence completion check used by
this test.

Keep nonblocking transition variants enabled and skip only the
blocking transition variants on MTK. The separate modeset
transition tests remain enabled.

This is a temporary test limitation until blocking atomic
transition completion is supported by the MTK DRM driver.
