[oe] [meta-oe][PATCH] opencv: Work around deprecated ffmpeg functions

The ffmpeg no longer makes use of the AVFMT_RAWPICTURE format, but
opencv still has code in it for dealing with this type of exported
format.  For now it is easier to work around it and allow the code to
compile and it will just not get used.  A future version of OpenCV
will remove the AVFMT_RAWPICTURE handler.
