Rebaseline foreign-object-skew.svg again.

This was rebaselined in https://src.chromium.org/viewvc/blink?view=rev&revision=155520 .
It looks like this made the debug bot start passing and the release bot stop
passing. Trying a second rebaseline, but if this doesn't work, we'll need to
figure out why the two bots are outputting different pixel data.

Also, I don't know what the original cause of the failure was, since the last
rebaseline had no contextual information.
