Mark pixel-crack-image-background-webkit-transform-scale failing on Mac

Test
virtual/gpu-rasterization/fast/images/pixel-crack-image-background-webkit-transform-scale.html
has been failing consistently on WebKit Mac10.10, WebKit Mac10.11
(retina) and mac10.10_blink_rel tryserver, for as far back as the
flakiness dashboard can show (which in practice is when
https://codereview.chromium.org/2265333002 added it to SlowTests; before
that it always timed out). However it always passes on other Mac bots.
