lib/debugfs: Add igt_assert_crc_equal

Browse Source 
Because of hash collisions tests should only ever compare crc
checksums for equality. Checking for inequality can result in random
failures.

To ensure this only expose and igt_assert function and use that.
Follow-up patches will rework the code for tests which don't follow
this requirement and try to compare for CRC inequality.

v2: Rebase on top of Matt's kms_plane changes.
