avcodec/librav1e: Pass through timestamps as opaque user data

Browse Source 
avcodec has no facilities to generate timestamps properly from
output frame numbers (and it would be wrong for VFR anyway),
so pass through the timestamps using rav1e's opaque user data
feature, which was added in v0.4.0.

This bumps the minimum librav1e version to 0.4.0.
