[lldb] Adjust windows xfails for D119167

A couple of additional tests pass with that patch. One new test fails
(because it's not testing a slightly different thing). I'll update it
later to restore the original meaning (I don't want to revert as the net
effect is still very positive), but for now this gets the bot green.
