ipcpd: Configure PFF from routing policy

The Packet Forwarding Function (PFF) was user-configurable using the
irm tool. However, this isn't really wanted since the PFF is dictated
by the routing algorithm. This moves the responsability for selecting
the correct PFF from the network admin to the unicast IPCP
implementation. Each routing policy now has to specify which PFF it
will use.
