ospfd: Self nbrs needs to be rebuilt when router ID changes.

Browse Source 
Some self nbrs are identified by router_id, these needs
to be rebuilt instead of just resetting router ID.
Possibly one could optimize for !(virtual | ptop) links
by doing oi->nbr_self->router_id = router_id instead.

Router ID will change once after startup config has been
read and zebra reports router ID, unless router ID has
been configured in ospf.

(cherry picked from commit 94266fa822baf9b9c9e10ac03ccec8ccf3ce0c98)
