lavf: use the new bitstream filter for extracting extradata
This also fixes a minor bug introduced in the codecpar conversion, where the termination condition for extracting the extradata does not match the actual extradata setting code. As a result, the packet durations made up by lavf go back to their values before the codecpar conversion. That is of little consequence since that code should eventually be dropped completely.
