sweet/go-build: set GOROOT correctly
Currently we just use a bare exec.Command and GOROOT may not be set
correctly for the first time we build it. That's an easy fix: use a
common.Go instead.
In the benchmark itself we still need to use a bare exec.Command, but
that's fine. Just set GOROOT in that case explicitly.
