improve average framerate calculation

Change Ice204e86 identified a problem with bitrate undershoot due to
low precision in the timestamps passed to the library. This patch
takes a different approach by calculating the duration of this frame

and letting the library average it out with higher precision
timestamps. This part of the fix only applies to vpxenc.

This patch also attempts to fix the problem for generic applications

calculating this frame's duration by the difference of this frame's
