net: lwip: wget: initialize dns if a hostname is used in a URL

Initialize dns servers if a hostname (vs ipaddr) is used in a URL.
Otherwise the wget will fail without displaying an error due to
dns_gethostbyname failing silently when no DNS servers are set unless
you have previously performed a 'dns <arg>' command.
