Gardening: virtual/softwarecompositing/repaint/resize-repaint.html needs manual rebaseline

[ NeedsRebaseline ] was added in https://codereview.chromium.org/371973004, then
removed in https://codereview.chromium.org/389393004 because rebaseline didn't work.
But the test is red on Linux Debug, so it needs some rebaseline.

I also tried using webkit-patch rebaseline-expectations and it didn't create a
new expectation.
