[PATCH i-g-t v3 1/1] tests/kms_async_flips: Skip Async flips on joiner output

[Santhosh Reddy Guddati]

Async flips are disallowed with joiner, but the test commit still
goes through and causes failures. Update the tests to skip on
joiner outputs.

V2: Skip tests only on joiner outputs (Kunal).
V3: Add a todo to remove workaround when async flips with joiner is
    supported in kernel.
