Subject: pppoe: T2219: move adding of default route to ip-(up|down) script

As PPPoE interfaces should be part of a VRF it is required that the default
can also be set into the specified VRF. The default way of PPP by setting the
"defaultroute" option does not take a VRF into account. In this case PPP
installs a Kernel route forwarding all default traffic over this interface.

This change installs a static route with metric 1 instead into the routing
table via FRR. This is not the same as a Kernel route in terms of metric 1
compared to 0 but it should do the trick.
