mac: Let ToTMac bot run webkit layout tests on macOS 10.12 swarming machines.

When the chromium.clang waterfall was converted to have its json files
autogenerated in https://chromium-review.googlesource.com/c/chromium/src/+/818075
ToTMac was the only bot that ran

  'isolated_scripts': 'chromium_isolated_scripts',

in waterfalls.pyl (to get telemetry tests and crash tests).
chromium_isolated_scripts also includes webkit_layout_tests, but until
https://chromium-review.googlesource.com/c/chromium/src/+/1060293 it was
excluded on ToTMac. Since that CL landed, ToTMac is the only tot bot running
layout tests. (We should probably add chromium_isolated_scripts to the other
bots too.)

It looks like layout tests don't fully pass on macOS 10.13 yet, so pin them to
10.12 swarming slaves, like the Mac10.13 Tests bot does.
