Some tests on ceph require changing the layout of new files, which is
forbidden when the files are encrypted. Add a test that touches a file
in $TEST_DIR and then tests it to see if it reports the
STATX_ATTR_ENCRYPTED flag, and does a _notrun if it's present.

Also add this requirement to the two ceph tests that change the layout.

Aren't you forgetting ceph/001?

Maybe this function could be in the 'common/encrypt' file instead.

Other than these 2 comments, I also agree that this approach is better
than hooking into the _ceph_create_file_layout() function.

Cheers,
