    Add a script to zero /etc/sysconfig/iptables at build time

    When including this element we empty the stock /etc/sysconfig/iptables
    file as shipped by the iptables rpm package. The reason for this is that
    puppet firewall has a hard time to cope with exiting rules when
    /etc/sysconfig/iptables is populated and the iptables service is not
    active. The referenced bug has a full explanation for the problem.

    Partial-Bug: #1657108
