overlay/065: Adapt test to relaxed rules
Kernel commit 708fa01597fa ("ovl: allow upperdir inside lowerdir")
changes the rules w.r.t allowed overlayfs configurations, so the
upperdir/lowerdir test that expects an error fails.
Adapt the test to check the configuration that is still not allowed
(lowerdir inside upperdir), which had no test coverage.
