[PATCH i-g-t] tests/kms_async_flips: Replace hard coded modifiers with async modifiers

[Santhosh Reddy Guddati]

Use the IN_FORMATS_ASYNC uAPI to get the list of async supported modifiers.
select the 2 unique modifiers from this list to test invalid async test,
removing the hard coded dependency across platforms.
