avformat/img2dec: probe JFIF/Exif header
Due to reasons, mpv doesn't pass filename when probing. mpv also sets default probescore threshold to 26. Since the current jpeg_probe implementation returns 25 until EOI, it means that the whole image needs to be probed to succeed. Worse, the whole image is not passed at once; increasingly large buffers are tried before that. Adding it up together, if many demuxers are enabled, moderately large JPEG files (few MB) can take several seconds to open, despite taking less than 1 second to actually decode. Therefore, adjust the heuristic to be more optimistic if proper JFIF or Exif segments are found. While not strictly required, the vast majority of JPEG-ish files have one or the other or both.
