Update QScreen::availableGeometry() on _NET_WORKAREA atom changes

When the window manager sets new workarea using the _NET_WORKAREA xcb
atom, QScreen::availableGeometry() does not react to that and returns an
invalid available geometry. This patch reacts to that change and updates
the QScreen property properly on xcb platform.
