avcodec/prosumer: fix some minor issues

avformat/movenc: implicitly enable negative CTS offsets for ismv

ISMV lacks any sort of edit list support, as well as tfxd is
effectively the PTS of the fragment for most intents and purposes.

Thus, if b-frames are requested without negative CTS offsets you
end up with N frames' worth of delay (tfxd PTS plus the CTS offset
of the first sample). Negative CTS offsets enable the first sample
to have CTS=DTS, and thus a/v desync due to b-frame reorder delay
is avoided.

lavfi/selectivecolor: fix neutral color filtering

Neutrals are supposed to be anything not black (0,0,0) and not white
(N,N,N).

Previous neutral filtering code was too strict by excluding colors with
any of its RGB component maxed instead of just the white color.
