Title: fix(coreos): remove refs to obsolete update-engine-reboot-manager

This was removed from CoreOS a while ago, so our unit file was having no effect.
See https://github.com/coreos/update_engine/pull/28

TESTING: Provision a new cluster, check to see that update-engine is still disabled and that the stop-reboot-manager.service is not installed.
