e2fsck: regression tests for INCOMPAT_MMP feature Add tests for the MMP feature - creating a filesystem with mke2fs and MMP enabled, enable/disable MMP with tune2fs, disabling the e2fsck MMP flag with tune2fs after a failed e2fsck, and e2fsck checking and fixing a corrupt MMP block. The MMP tests need to be run from a real disk, not tmpfs, because tmpfs doesn't support O_DIRECT reads, which MMP uses to ensure that reads from the MMP block are not filled from the page cache. Using a local disk does not slow down the tests noticably, since they wait to detect if the MMP block is being modified.

tests: fix mmp tests on hard 4k devices Several of the mmp tests were failing on an s390 guest because direct IO cannot be done on sub-sector sizes, and they were doing 1k IOs to files on a 4k logical/physical device. A few tests could just be changed to 4k, but others needed fixed up output as well. With this I have all tests passing on s390 again.
