[PATCH XTS v2 2/2] xts5: fix XSetDeviceFocus-5

[Peter Hutterer]

t003() selects for key events on the root window. t005() takes over and then
complains when the focus correctly follows the pointer and an event is
delivered to the root window. If you don't expect events on the root window,
unselect them first.

We could also XCloseDisplay() at the end of each test but who knows what that
does to the other tests.

Changes to v1:
- hah! there is a macro for the "no event" class after all. use that.

Chase, I figured your rev-by still stands given that this is the same effect
but much saner.
