Mp4: fixed potential overflow in ngx_http_mp4_crop_stts_data(). Both "count" and "duration" variables are 32-bit, so their product might potentially overflow. It is used to reduce 64-bit start_time variable, and with very large start_time this can result in incorrect seeking. Found by Coverity (CID 1499904).
