util: Use default resolver behavior in util::dns::Resolver
As of this commit, we are using the default behavior of
boost::asio::ip::resolver (only return IPv4 addresses if a non-loopback
IPv4 address is configured for the system; only return IPv6 addresses if
a non-loopback IPv6 address is configured for the system).
Unit tests are now conditioned upon availability of IPv4/IPv6 and will
not fail if IPv4 or IPv6 addresses cannot be resolved.
