bgpd: to select bgp self peer prefix on rr case with bgp-lu

This commit addresses an issue that happens when using bgp
labeled unicast peering with a rr client, with a received prefix
which is the local ip address of the bgp session.

When using bgp ipv4 labeled session, the local prefix is
received by a peer, and finds out that the proposed prefix
and its next-hop are the same. To avoid a route loop locally,
no nexthop entry is referenced for that prefix, and the route
will not be selected.

As it has been done for ipv4-unicast, apply the following fix
for labeled address families: when the received peer is
a route reflector, the prefix has to be selected, even if the
route can not be installed locally.
