Explicitly specify the xattr namespace required for tests. This allows tests to be skipped correctly for filesystems that don't support all xattr namespaces. This changes all tests that require anything other than the "user" xattr namespace. When called without arguments as before, _require_attrs() still defaults to the "user" namespace, so those tests do not need to be changed.
