misc/dashboard/builder: record build result on dashboard

This is part one of two changes intended to make it easier to debug builder failures.

runOutput allows us to control the io.Writer passed to a subcommand. The intention is to add additional debugging information before and after the build which will then be capture and sent to the dashboard.

In this proposal, the only additional information is the build status. See http://build.golang.org/log/e7b5bf435b4de1913fc61781b3295fb3f03aeb6e

Thanks. In followup CLs I'd like to use this facility to log a few
details (env vars, build start time, etc).
