[igt-dev] [PATCH i-g-t 08/12] tests/kms_rotation_crc: Always run the flip tests when available.

[Maarten Lankhorst <maarten.lankhorst@linux.intel.com>]

The -flip tests are the same, but with a pageflip at the end,
since the test is otherwise the same, run the test once with flips
always enabled when possible.
