I made a tracking bug. This has already been turned on for some bots. This CL
just continues the rollout to more bots. See:
https://cs.chromium.org/search/?q=force_mac_toolchain+-file:json&sq=package:c...

If it already works on some builds, why not turn it on everywhere?

But lgtm if you want to flip just this bot for now.

Some bots will inevitably be misconfigured. Doing one set at a time minimizes
disruption.

I've landed https://codereview.chromium.org/2102783002/, so this CL can be
