Sindhu Parvathi Gopinathan bc06ff90f5 bgpd: EVPN fix per rd specific type-2 json output
Current Issue:

paths key is not there for
'show bgp l2vpn evpn route rd <rd-id> mac <mac> json' uses
evpn prefix as key for each path.
Replace the evpn prefix with "paths".
This aligned with overall EVPN RIB json output like
'show bgp l2vpn evpn route json'
'show bgp l2vpn evpn route rd <> type 2 json'

Fix:

paths key is added instead of prefix info.

Ticket:#4087461

Issue:4087461
