decodebin2: Handle raw streams we don't want.

If a file contains raw streams (not requiring a decoder) that we do
not want (expose-all-streams == FALSE), we would previously consider
those of unknown-type (missing a decoder) ... whereas in fact it was just
because they don't need decoders.

This only applies if expose-all-streams is FALSE.
