bgpd: Ensure evpn local table display shows route send status

evpn has a concept of `local` tables where the evpn routes
are actually converted into underlying routes/neighbor
table entries( or vice versa ).  Then this local route
is propagated to the global evpn l2vpn table and sent
to the peers.  Certain show commands in evpn look
operate on the local table but make the output look
like the data has not been sent to the peer.  This
is confusing for the operator.  Modify the code
such that local tables get a `Local BGP table not advertised`
in the place where the code talks about whom has received
the data or not.

Example:
torm11# show bgp l2vpn evpn route vni 1000 mac 8a:a1:cc:73:a3:ac ip 45.0.0.5
BGP routing table entry for [2]:[0]:[48]:[8a:a1:cc:73:a3:ac]:[32]:[45.0.0.5]
Paths: (2 available, best #2)
  Local BGP table not advertised
  Route [2]:[0]:[48]:[8a:a1:cc:73:a3:ac]:[32]:[45.0.0.5] VNI 1000
