GStreamer: don't use xvimagesink when Qt is not using Xcb.
We need a native X window handle to be able to use xvimagesink. If Qt doesn't use the Xcb platform plugin, don't try to use that element. This patch makes QVideoWidget usable when the system doesn't run X11 but xvimagesink is installed anyway. Widget and window controls become invalid and the plugin therefore falls back to the renderer control.
