wavparse: do not include codec_data on raw audio caps

Browse source 
If the wav header contains an extended chunk, we want to keep
the codec_data field, but not for raw audio.

This fixes some elements (such as adder) from failing to intersect
raw audio caps which would otherwise be intersectable.
