[PATCH i-g-t] lib/igt_kms: Update igt_fit_modes_in_bw to add legacy commit check

[Karthik B S]

Currently igt_fit_modes_in_bw is only checking for atomic commit but the
igt_override_all_active_output_modes_to_fit_bw function which it is
wrapping actually has support for legacy commit as well.

To handle this, add support for legacy commit check as well.
