avformat/webm_chunk: Remove unnecessary variable
chunk_start_index (which was set via an option) was only used to initialize chunk_index and otherwise unused. So initialize chunk_index directly via the option and remove chunk_start_index. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
