avformat/smacker: Fix duration for PCM audio

For non-PCM audio, a Smacker frame contains the size of the decoded
audio in the first four bytes of the audio packet data; for PCM data,
said information would be redundant and according to [1] this field does
not exist. Therefore this commit sets the duration and timestamps
properly for PCM audio.
