xfs: test handling of invalid inode modes

Set all possible file type values for different types of files
and verify that xfs_repair detects the correct errors.

When setting invalid file type values (e.g. core.mode = 0170644),
all files are expected to have been junked by xfs_repair.

When setting valid file type values to non matching file types,
xfs_repair would either detect wrong format and junk the file, e.g.:
  would have junked entry "DATA" in directory PARENT_INO
or detect a ftype mismatch error, e.g.:
  would fix ftype mismatch (5/3) in directory/child PARENT_INO/FIFO_INO

If ftype feature is enabled, when setting file type to one of the
special types (i.e. FIFO(1), CHRDEV(2),BLKDEV(6),SOCKET(14)),
xfs_repair is expected to detect ftype mismatch error. Otherwise,
xfs_repair is not expected to detect ftype mismatch error.
