vp9: Adjustment to active_best_quality for inter_frame, 1 pass vbr.

Change only affects 1 pass vbr.

Use a q value somewhat larger (~6%) than avg_frame_qindex[INTER]
as basis for active_best_quality for inter-frames.
And use the minium of this (avg_frame_qindex) and the active_worst_quality.

This reduces some overshoot in ytlive clips.
Overall small but positive average increase in metrics (up on average ~0.2%).
