output: stop assuming a frame is pending in init

Browse source 
- The DRM backend initially doesn't have a frame scheduled initially.
  However the compositor is expected to set a mode to start the
  rendering loop (frame_pending is set to true in drm_crtc_pageflip).
- The headless and X11 backends have a timer to schedule frames, so they
  ignore this hint completely.
- The Wayland backend renders a fake frame to start the rendering loop.
  It's the only case where a frame is pending on init, move the
  assumption there.
