demux_mkv: trust keyframe flags for TrueHD

Browse Source 
TrueHD is a fucked up audio codec with extremely small frame sizes. Some
of these frames start with full headers, which are usually marked as
keyframes, and from which decoding can be started (or at least that's
what you'd expect).

So for such tracks we should probably trust the keyframe flags. Doesn't
really improve seek behavior, though.
