fix(networks): skip nexthop and default lines when parsing IPv6 routes

Browse Source 
`ip -6 route` output for ECMP/multipath routes carries `nexthop` continuation
lines, and a `default` route has no network prefix. donets() treated both as
networks and added bogus entries to the networks table. Skip them alongside
the existing link-local/unreachable/via/lo filtering.

Recovered from the unmerged lenovobuild branch (original 7094ba0c).
