VCMPacket: Set VCMNaluCompleteness for generic codecs

Browse Source 
We previously always set VCMNaluCompleteness to kNaluComplete for
kVideoCodecGeneric, which seems wrong. This CL fixes that and also
cleans up the code a bit. The logic for VP8, VP9, and H264
should be exactly preserved. This CL also updates the test to use
kVideoCodecGeneric instead of kVideoCodecUnknown. kVideoCodecUnknown
has no purpose and should be removed.
