Bug 1382564 - Use the information from bug 1374940 with `mach artifact toolchain`. r=gps Bug 1374940 adds a MOZ_TOOLCHAINS environment variable with a list of path@task-id strings, where task-id is corresponding to the (possibly optimized) toolchain job, and path corresponding to the toolchain-artifact defined for that toolchain job. We want to use that to pull artifacts instead of tooltool packages.
