Mac10.13 webkit_layout_tests: Update JPEGs

Recently, libjpeg-turbo was updated to v2.0.1 [1].
Because Mac10.13 is not part of CQ, its altered JPEGs weren't included
in the update. This caused the Mac10.13 bots to start failing.

This CL updates Mac10.13's JPEG images to match the new output, which
includes AVX2-accelerated decoding and new fancy upscaling on 4:4:0.
