Previously, varlink or dbus methods return io.systemd.Resolve.NoNameServers or BUS_ERROR_NO_NAME_SERVERS if an empty hostname is provided, and thus nss-resolve returns NSS_STATUS_TRYAGAIN. That causes getaddrinfo() returns 'Temporary failure in name resolution' instead of 'Name or service not known'. This makes calling varlink or dbus method with an empty hostname result -EINVAL, and hence nss-resolve returns NSS_STATUS_NOTFOUND. Fixes RHBZ#2039854 (https://bugzilla.redhat.com/show_bug.cgi?id=2039854).
