ext4dev is no longer supported by kernel so we really need to get rid of
it entirely from e2fsprogs.
This patch removes any occurrence of ext4dev and test_fs flag from the
e2fsprogs tools with one exception. Out of paranoia we can still leave
the possibility to remove test_fs flag (EXT2_FLAGS_TEST_FILESYS) from
the file system using e2fsck by specifying clear_test_fs_flag option in
the e2fsck.config file.
