sockets: don't call getaddrinfo with AI_ADDRCONFIG

Browse source 
On linux, using AI_ADDRCONFIG causes getaddrinfo to return no ip
address for localhost when only the loopback connection is
active. Also, we only get ipv4 addresses anyway due to specifying
ai_family = AF_INET, therefore the AI_ADDRCONFIG flag in not necessary
anyway.
