zebra: Trust kernel and System routes
If we receive a valid message from the kernel that
is either a kernel or system route, we should trust
that the route is legit and just use it.
Old behavior:
K * 172.22.0.0/15 [0/0] via 172.22.2.254, eva_dummy1 inactive, 00:00:16
New Behavior:
K>* 172.22.0.0/15 [0/0] via 172.22.2.254, eva_dummy1, 00:02:35
