hw/xwin: More adjustments to multiwindow mode focus handling

The previous change is not enough, as WM_KILLFOCUS can apparently be
sent to the window losing focus after WM_ACTIVATE has been sent to
the window gaining focus.

Try using WM_SETFOCUS instead, as that has the correct ordering and seems
more logical.

The test "!pWin || !pWin->overrideRedirect" is confusingly written: It's
true if:

(a) pWin is NULL (= X window doesn't exist, shouldn't happen), or
(b) pWin->overrideRedirect is FALSE

i.e. the intended effect is "don't give focus to override redirect windows"

There seem to be some cases where this still isn't quite correct: A
reproduction isn't known, but it seems to be related to minimizing a
maximized Windows window, and having window activation move to a
maximized X window beneath it.
