[net/dns] Hardcode DnsConfig.timeout to 1 second.
Currently, it is read from OS (if available) or set to 5 seconds (on Windows). In some cases the OS provides ridiculous values (30s on Mac).
This change hard-codes the timeout to 1 second, which is the default used by getaddrinfo on Windows and Mac.
