Ignore Ogg streams of unknown type but keep track of them
Ignore Ogg streams of unknown type but keep track of them

This fixes an issue when there is an Ogg stream in the file that is in a
type unknown to VLC it would forget about this stream ever existing and
therefore putting out errors whenever it encountered a new page with the
forgotten stream serial number:

    ogg demux error: Broken Ogg stream (serialno) mismatch
