matroskaparse: calculate segment duration after parsing all the IDs
Since the segment duration is given in terms of the GST_MATROSKA_ID_TIMECODESCALE we should only convert it into nanoseconds when we are sure that any scale specified in the file has been read. https://bugzilla.gnome.org/show_bug.cgi?id=650258
