(MODULES-2159) ignore the --connlimit-saddr switch when parsing rules

Workaround for https://tickets.puppetlabs.com/browse/MODULES-2159 (as described by Greg Murphy in that ticket)

On some distributions (notably on Ubuntu 14.04 and above, and Centos7 and above) the --connlimit-saddr switch is added after the rule is applied causing rule_to_hash to ignore the rule.  Puppet then attempts (and failes) to re-create the rule every time it runs.
