videosoftware: Added hack to bypass xfb just so fifoplayer works.

Fifoplayer depends on the old behaviour of videosoftware (and the other
hardware backends in non virtual/real xfb modes) where the framebuffer
gets rendered directly to the screen.

Really fifoplayer should call BeginFrame/EndFrame when it finished
rendering a frame, but adding this hack back in is simpler.
