parameterize logrotate options

Add support for OSfamily specific logrotate options. Fixes the problem with Suse and the missing ```missingok``` option.

Possible successor of https://github.com/ghoneycutt/puppet-module-rsyslog/pull/58, please take this as example only. I haven't had time to test this in real life yet.
By default Solaris will still not use logrotate. It is possible to activate $logrotate_present for Solaris too, therefore I test the potential output here. No functionality change.
