avcodec/encode: Set AV_PKT_FLAG_KEY based upon AV_CODEC_PROP_INTRA_ONLY

Browse Source 
Currently, the AV_PKT_FLAG_KEY is automatically set for audio encoders;
yet this is wrong, as both MLP and TrueHD have non-keyframes. So set it
based upon AV_CODEC_PROP_INTRA_ONLY (from the corresponding
AVCodecDescriptor) instead. This also sets it for some video codecs,
which is intended.
