Subject: [RFC PATCH mtd-utils 107/110] tests: ubifs_tools: fsck_tests: Add bad images fixing test
For kinds of inconsistent UBIFS images(which can simulate corruptions
caused by some potentional UBIFS bug), check the result of fsck.
This testcase mainly checks whether the behavior is in expected after
repairing specific inconsistent UBIFS image.
