libhevcenc: fix bitrate overshoot when lookahead is disabled
When rc lookahead is disabled, next frame encode context becomes NULL.
This context is used to signal end of gop. As this is NULL rc does not
know the end of gop causing over consumption of bits. Rely on intraframe
interval to resolve this.
Also, as there is no scene change detection, default all pics to single scene.
