flow utility shows incorrect IP for IPv6 flows

[amit surana]

Flow entry is wrong when a VM pings a destination learnt via BGPaaS VM. Fd66::4 is pinging 2001:db8:0:f102::1 (which was learnt via BGPaaS VM). The pings work fine and packets on the wire are v6 packets. However, flow entry looks corrupted.

Expand the local buffer to hold ipv6 address string

The buffer that is used to hold the string that represents the ipv6
address is only 16bytes strong. Expand it to INET6_ADDRSTRLEN (or
46 bytes) in size.
