Do not allow fullscreen/maximized windows to expand beyond client rect

Automatic layouting of widgets still managed to layout maximized and
fullscreen windows larger than client rect in Symbian in some cases.
Fixed by limiting window dimensions to client area boundaries in
setGeometry_sys if the window is maximized or fullscreen.
