[PATCH i-g-t v8 2/2] lib/igt_kms.c: Enforce strict check for bigjoiner_possible

[Santhosh Reddy Guddati]

update bigjoiner_mode_found to check for ultrajoiner possibility.
This ensures that the mode is only set to bigjoiner if ultrajoiner
is not possible.

v8: rebase and check fot ultra joiner possibility.
