lib: add prefix support for evpn route type 5

The requirement from draft-ietf-bess-evpn-prefix-advertisement-03
mentions that the Eth-Tag ID, IP Prefix Length and IP Prefix will be
part of the route key used by BGP. The ip prefix length is then appended
to the evpn_addr. In addition to this, the ethernet tag ID is reused.
