[PATCH i-g-t] igt/kms: Skip tests when PSR cannot be enabled.

[Dhinakaran Pandiyan]

The frontbuffer_tracking PSR tests fail if PSR cannot be activated when
there is sink support. But, there are several other requirements related to
mode timings that have to be satisfied before PSR can be enabled. No reason
to fail these tests when PSR cannot be enabled.
