Update efw-iptables version number and API version

As the firewall API has changed in regards to moving a way from
a string based implementation to a struct based implementation, the
older eurephia firewall module will not work any longer.

To make sure nothing bad happens, enforce that the efw-iptables
module is at least using API version 2.  Also updated the module
version to reflect some changes as well.
