vp9_ratectrl: change ARF overlays rate correction factor

Browse Source 
ARF overlays now use the same rate correction factor as regular inter
frames, further testing would be needed to see if it makes sense to use
a completely separate rate correction factor for ARF overlays.

$ vpxenc --cpu-used=5  --fps=50/1 --target-bitrate=2000
