When not using dedicated replication systemd still puts init scripts
down, which take a long time to restart/start. upstart scripts get
around this by setting blank scripts.
Now that we are using a service dict we can do better by defining an
"service_en" flag and not setting up scripts when the service isn't
enabled.
Additionally, the systemd tempfiles and init files were not using the
appropriate "program_binary" variable at all, this has been fixed.
