Increase video-rotation test tolerance, add vp9 version. (KhronosGrou…

…p#3262)

Speed focused software yuv conversion libraries may be off by more
than 5 points in a channel for values near the channel maximum.

There's also no reason we can't have a vp9 version of this test, so
add encodes for clients who want to test w/o proprietary codecs.

Run both h264 and vp9 tests if supported.
