Lower threshold to skip YUV-RGB converison tests
Lower the threshold for skipping the YUV<->RGB conversion tests from
39 * 1024 * 1024 to 35 * 1024 * 1024.
A test image of size 11267 x 3328 (bit depth=12, YUV 4:4:4) causes a
sanitizer build to spend 3 to 6 seconds in avifImageYUVToRGB() and
avifImageRGBToYUV().
