Use mac hermetic toolchain for WebRTC Chromium FYI tests.

It looks like "mac_toolchain" sets the FORCE_MAC_TOOLCHAIN environment
variable to 0 (see [1]), which disables the hermetic toolchain accorging
to [2].

Recipes

If you're here to make a change to ‘recipes’ (the code located in scripts/slave/recipes*), please take a look at the README for more information pertaining to recipes.

Style

The preferred style is PEP8 with two-space indent; that is, the Chromium Python style. Functions use lowercase_with_underscores, with the exception of the special functions RunSteps and RunTests in recipes. Use yapf (git cl format --no-clang-format) to autoformat new code.
