avcodec/videotoolboxenc: Set default bitrate to zero

Zero is auto mode. From the doc of videotoolbox:

   The default bit rate is zero, which indicates that the video
   encoder should determine the size of compressed data.

Before the patch, the default bitrate is 200000 setting by
avcodec/options_table, which doesn't work for most of cases.
