isisd, ospf6d, ripngd: Do not allow v6 LL's to be `redist connected` in
The rib process of handling routes has been unified a bit more
and as a result v6 LL routes are now showing up as a result
of a `redistribute connected`. Doing anything with these
routes is a policy decision that should be enforced by the
individual routing daemons not by zebra. As such add a bit
of code to isisd, ripngd and opsf6d to handle them. The bgp daemon
already handles this situation.
