Ironically, despite being introduced to make YUVJ unnecessary, the new YUV negotiation logic failed to actually negotiate YUVJ formats themselves correctly, leading to errors when passing YUVJ frames into a filter graph. (They were effectively treated like RGB or Grayscale formats, rather than as forced-full-range YUV, and hence did not have their colorspace matrix correctly negotiated) Fix this by splitting off the YUVJ check from ff_fmt_is_regular_yuv(). Obviously, we can trivially undo this change again once YUVJ is actually deleted from the codebase. Fixes: #11179
