env/linux-x86-sid: add cloudbuild configuration

Also, update to the latest tag rather than one from 2019. This is in
preparation for changing the host config to use a specific image tag
instead of baking the image tag into every docker image.

This change will allow us to keep a separate 'cloudbuild' tag from the
tag used for the main bulder. This tag can be updated weekly, allowing
us to run a second builder in parallel to determine when we want to
update to a newer image.

For golang/go#56673
