Subject: [PATCH] Allow listen.ipaddr to reference an IPv6-only host

In 5452b13cefa3b30f1da467ff5d68b3c1aa471188, these lines were added
which effectively result in a listen.ipaddr only allowing hostnames to
resolve to IPv4 addresses. With a hostname with only a IPv6 address,
it'll bail with the error message:

radiusd: #### Opening IP addresses and Ports ####
listen {
        type = "auth"
Failed resolving "ipv6.cipherboy.com" to IPv4 address:
    Name or service not known

This directly contradicts the language in the default configuration
file, so support resolving both IPv4-only and IPv6-only hostnames.
