bgpd: Fix received-routes detail

Browse Source 
The command `show bgp ipv4 uni neigh A.B.C.D received-routes detail`
was not displaying anything.

Fix the code to display the received routes from the ones that
have been filtered.  In this case we need to fudge up a bgp_dest
and a bgp_path_info to make it work.

Old output:

janelle.pinkbelly.org# show bgp ipv4 uni neighbors 192.168.119.224 received-routes detail
BGP table version is 1711405, local router ID is 192.168.44.1, vrf id 0
Default local pref 100, local AS 64539

Total number of prefixes 3 (3 filtered)

New output:
