Add expected failures for ZFS

- :f_flag fails on ZFS because UF_IMMUTABLE isn't supported [1].
- :v_flag fails on ZFS because the mode for foo is [always] updated
  unnecessarily.

get_filesystem(..) (supporting function that was added to the test script)
is based on equivalent logic in usr.bin/extattr/tests/extattr_test.sh .
