More filesystems have grown freeze capability, so rather than
hardcoding several in _supported_fs, make tests 068 and 280
generic and then add a new _require_freeze() which checks whether
the fs under test can be frozen before beginning the test.
Minor other cleanups to 280:
- remove extra _supported_fs line
- clear $seq.full before beginning
