tst_QGL::graphicsViewClipping: Wait for viewport's window handle

The QWidget overload of qWaitForWindowExposed waits for the widget's
top level QWindow, which for the viewport is the graphics-view.

We want to explicitly wait for the viewport to be exposed, as the
viewport is covering the whole graphics-view, preventing it from
being exposed. See a6991376c.
