tests: add regression tests for group descriptors with bad checksums

Add tests to examine how e2fsck deals with (a) the block bitmap being
corrupt; (b) the inode bitmap being corrupt; (c) the bitmap checksums
being incorrect (but the bitmaps are fine); and (d) the group
descriptor checksum itself is incorrect.
