vp9 svc: Make top layer non-ref: for 2 TL case

Multimedia / WebM - Marco Paniconi [google.com] - 31 January 2018 17:17 EST

Only affects 2 temporal layer case. Modified the flags for 2 temporal layers to make top layer (top spatial, top temporal) a non-reference frame, conistent with the 3 TL case.

Add mismatch check to the datarate test of changing svc pattern on the fly, which is test for 2 temporal layers.

This re-applies the change: 254e2f5501d, that was reverted in: 658eb1d675.
