    g_network_monitor_base_can_reach: Check for default route after enumerating.
    
    Enumerate the GSocketConnectable before checking for a default route.
    For some connectable types this will involve a DNS lookup.  This will
    elminate false positives for hosts behind a VPN since DNS lookup will
    fail if the VPN is not connected.
