Fix hang on "Loading IRCd configuration" if DNS is not working correctly.

Browse Source 
For example if the 1st DNS resolver is refusing or ignoring requests.
We forgot to call unrealdns_timeout() in the waiting loop, so DNS requests
never timed out and c-ares didn't try the 2nd/3rd server either.
