Add IPv6 local interface address handling

Browse source 
With the '--host' flag, a local interface IP address can be set on which
the collector listens for incoming flows. Since now, this only worked
with IPv4 addresses (using the default 0.0.0.0 interface). The commit
adds handling of passed-in IPv6 addresses by identifying ":" and then
switching to the AF_INET6 socket family.
