Tweak github action to deal with no space error

The github build action is erorring out with a `no space left on
device error` when trying to download the docker image
`k8s.gcr.io/kube-cross:v1.12.12-1` to run the build. That image
is 1.87GB big, and the `easimon/maximize-build-space` action was
leaving only 512MB free on the root filesystem.

We are completely removing that action to see if the default 14GB
of disk space allocated by github actions are enough for the build

Additionally, we are removing the `actions/setup-go` as well,
since it should not be needed in this pipeline.
