[PATCH v5 2/4] tests/kms_async_flips: Check for atomic async flip cap

["André Almeida" <andrealmeid@igalia.com>]

If a driver doesn't support doing an async flip through the atomic uAPI,
the atomic tests fails. Instead of failing, create a function that
checks for this capability and skip the test if is unsupported.
