avcodec/libopenh264dec: Increase array sizes, fix stack-buffer overread
av_image_copy() expects an array of four pointers and linesizes according to its declaration; it currently only pointers that are actually in use (depending upon the pixel format), but this might change at any time. It has already happened for the linesizes in d7bc52bf and so increasing their array fixes a stack-buffer overread. This fixes a -Wstringop-overflow= and -Wstringop-overread warning from GCC 11.2.
