We already have 221 for accesses through the page cache, but it is better to create a new file for O_DIRECT instead of integrating those test cases into 221. This way, we can make use of _supported_cache_modes (and _default_cache_mode) so the test is automatically skipped on filesystems that do not support O_DIRECT. As part of the split, add _supported_cache_modes to 221. With that, it no longer fails when run with -c none or -c directsync.
