firewallmngr: add package Makefile
* add Makefile that adds Device.Firewall. and Device.NAT. tr181 data model objects as a micro service * add CONFIG_FIREWALLMNGR_PORT_TRIGGER option, which, when enabled includes support for Device.NAT.PortTrigger. object and selects appropriate kmod dependencies, and is enabled by default * copy port-trigger scripts to firewallmngr, as it might be archived in future
