proposed fix, fetch the number of the last audio track

I add a patch that fixes this the same as recent versions of libdiscid:
https://github.com/metabrainz/libdiscid/blob/eef09db2bcf5c611025fe62215c1435d7b9d9b88/src/toc.c#L54

Previous versions of libdiscid did it different. This way has the advantage to
cope with discs that have multiple data tracks.

Also note that data tracks at the start of the TOC (like done with PC games
sometimes) don't get cut off, since the first track is expected to be track 1.

Tested with the test program mentioned above and various discs (with and
without data tracks). Compared with the result from libdiscid.

The patch was done against current git master.
