fff-gateway: Add script to load vlan defaults

With this script a user can load easy a vlan default setting to
/etc/config/gateway

We use the same port configuration as the node firmware except
the Batman-adv ports are use as Babel ports

With this script it is easier to use the layer 3 firmware for user
without knowledge for openwrt vlan settings
