vp9-realtime: Enable alt_ref at speed 5, for live.
Enable alt_ref and compound prediction at speed 5.
For 1 pass VBR mode, when lag > 0.
Gain for Live set: ~3% gain on average, several
clips have gains ~5-15%.
Encoder fps decrease ~5-10%, on desktop with 4 threads.
For now enable it only for resolutions <= 1280x720.
