tests: make cp-mv-enotsup-xattr independent of the host file system

* tests/cp-mv-enotsup-xattr: Create a file system from which to copy
the xattrs so that the test is not skipped if the host file system
does not have user_xattr support.  Also don't erroneously fail when
built without xattr support.
