[bug#62802] [PATCH 4/4] services: syslog: Log auth.info to /var/log/secure in default configuration.

[Maxim Cournoyer]

This causes authentication failures such as those generated by SSH brute force
attacks to appear in /var/log/secure, which is picked up by tools such as
fail2ban.

* gnu/services/base.scm (%default-syslog.conf): Add a auth.info selector for
the /var/log/secure log.
