vp9: Small ajustment to settings gf_interval, 1 pass vbr.

Browse Source 
Add a max condition and lower the min value.

No change in behavior (metrics for yt live set) for the
default min/max_gf_interval=4/16 settings.
Small positive change when min/max_gf_interval=7/16
(for 60fps clips on ytlive set).
