Build k8s using latest commit of golang

Browse source 
Run "gimme master" and use the newly built binaries. Adjust
GOROOT_BOOTSTRAP so we can use the golang that is already
on disk to build the new commit from golang.

To enable this, edit `.go-version` and set the version to
```
devel
```

and then run `make quick-release` (for example)
