[test] update RoutingManager unit test to check default-route (#7940)

Browse Source 
This commit updates `test_routing_manager` unit test to validate the
behavior of `RoutingMangaer` related to default route prefix (when AIL
routers advertise default route in RA header or as `::/0` prefix in an
RIO).
