[PATCH 8/9] doc: name the supported log levels for ipt_LOG

[Jan Engelhardt <jengelh@inai.de>]

Leonardo Ferreira da Silva Boiko lets it be known that syslogd.conf may
not exist on certain systems. Referencing that manpage is not a good
idea in any case, I believe, since the strings that are accepted are
defined by iptables and not a syslog implementation.
