vp9: Datarate test: modify frame flags for 3 TL. Modify the frame flags to update the ARF on top layer, for the tests: VP9/DatarateTestVP9Large.BasicRateTargeting3TemporalLayers VP9/DatarateTestVP9Large.BasicRateTargeting3TemporalLayersFrameDropping This is needed to fix the encode/decoder mismatches caused by 863f860, and removed in the revert e9b7f98.
