QVideoWidget: fixed setFullScreen(false) on the Xcb platform.

Fixed exiting fullscreen when a QVideoWidget is embedded in another QWidget.
Requires change I3616dc0f in qtbase to work.
Because of a bug in some X window managers, the order in which
setWindowFlags() and showNormal() are called has been changed.
