stack-tracker: Don't sort O-R's under guard window on top

Browse Source 
As of "stack-tracker: Keep override redirect windows on top"
(e3d5bc077d0ee5dc0368f99d22ce352c696644b9), we always sorted all
override redirect on top of regular windows, as so is expected by
regular override redirect windows. This had an unwanted consequence,
however, which is that we should still not sort such override redirect
windows on top if they are behind the guard window, as that'd result in
windows hidden behind it now getting restacked anyway.

Fix this by only sorting the override redirect windows that are found
above the guard window on top. This fixes the override-redirect stacking
test.
