Subject: [PATCH] Use CircleCI parallelism

This commit uses the CircleCI parallelism features, combined with the
last changes in promu that enables this.

Now all the pull requests will be built with all the platforms again, in
less than 20 minutes.

A side effect is that we now build Prometheus for 7 more os/arch combos:
darwin-arm64 / illumos-amd64 / linux-mips / linux-mipsle /
freebsd-arm64 / netbsd-arm64 / openbsd-arm64
