etc: systemd services: switch to "journal" for output and error logging.

The "syslog" method has been deprecated for years, and issues a warning:

  Standard output type syslog is obsolete, automatically updating to
  journal. Please update your unit file, and consider removing the setting
  altogether.

Fixes: #48323

* etc/guix-daemon.service.in (StandardOutput): Use "journal"
(StandardError): Likewise.
* etc/guix-publish.service.in (StandardOutput): Likewise.
(StandardError): Likewise.
