Run the t_immutable test program for immutable/append-only files
and directories in an overlayfs upper directory.
This test is similar and was derived from generic/079, but
the original test is _notrun on overlay mount because FS_IOC_GETFLAGS
FS_IOC_SETFLAGS ioctls fail on overlay directory inodes.

Eryu,
My previous statement that overlayfs does not enforce directory immutable
directory inodes was wrong. The directory tests do pass because overlayfs
does the right thing.
So only failures are for open(O_TRUNC) and truncate() of IS_APPEND
regular file inodes, which shouldn't be too hard to fix:

truncate(/mnt/scratch/ovl-mnt/t_immutable/append-only.f, 0) did not fail
testing immutable...PASS.
testing append-only...FAILED! (7 tests failed)
