staticd: register to interface events related with non default vrf

Browse Source 
in addition to non default vrf, once a new vrf is available, the static
daemon registers to events from that vrf, including presence of
interfaces. this permits to create static route with nexthop=interface.
Reversely, an unregistration is scheduled too when vrf disappears.
