services: certbot: Don't try to renew certificates on activation.

Because it takes too much time and it requires networking.

Thanks to Mathieu Othacehe for suggesting this.

* gnu/services/certbot.scm (certbot-activation): Do not run the renewal
command, copy its path to a fixed location, display it, so that the user can
run the command when they want.
