Subject: home: shepherd: Add daemonize? option to configuration.

* gnu/home/services/shepherd.scm (home-shepherd-configuration):
Add DAEMONIZE?.
(home-shepherd-configuration-file): Use CONFIG argument instead of two
separate SERVICES and SHEPHERD, respect DAEMONIZE?.
(ensure-shepherd-gexp, launch-shepherd-gexp,
shepherd-xdg-configuration-files): Adjust according to arguments changes in
HOME-SHEPHERD-CONFIGURATION-FILE.
