lavf: move the packet keyframe setting code.

Browse Source 
compute_pkt_fields() is for unreliable estimates or guessing. The
keyframe information from the parser is (at least in theory) reliable,
so it should be used even when the other guessing is disabled with the
AVFMT_FLAG_NOFILLIN flag.

Therefore, move setting the packet keyframe flag based on parser
information from compute_pkt_fields() to read_frame_internal().
