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.
solaris10 and 11 were not using logrotate before. This seems to change that.
