ext/ffmpeg/gstffmpegcodecmap.c: Use AVPALETTE_SIZE macro instead of magic value for clarity.

Browse source 
Original commit message from CVS:
* ext/ffmpeg/gstffmpegcodecmap.c: (gst_ffmpeg_get_palette),
(gst_ffmpeg_set_palette):
Use AVPALETTE_SIZE macro instead of magic value for clarity.
* ext/ffmpeg/gstffmpegdec.c: (gst_ffmpegdec_frame):
In GStreamer, the size of the palette is not part of
GST_BUFFER_SIZE, so adjust buffer size of outgoing buffers
accordingly if there's a palette (fixes #327028, based on
patch by: Fabrizio Gennari).
