[net] use AF_INET hint for GetFQDN()
I noticed that on nodes with not properly configured IPv6 DNS resolver,
GetFQDN() would take quite a long time (~5 seconds) even if it
eventually returns the name. This patch addresses the issue, adding
the AF_INET hint for 'ai_family' when invoking getaddrinfo(). Doing so
is in sync with the set of hints provided for the invocation of
getaddrinfo() in the context of HostPort::ResolveAddresses().
