net: set ADDRCONFIG DNS hint in connections

Browse Source 
b85a50b6da5bbd7e9c8902a13dfbe1a142fd786a removed the implicit
setting of DNS hints when creating a connection. This caused some
of the pi2 machines to become flaky. This commit restores the
implicit dns.ADDRCONFIG hint, but not dns.V4MAPPED.
