    Use ndirector, not serial in DNS director.
    
    The test case for this doesn't trigger, but the failing VCL (when
    given in a file with -f) looks like:
    
    director squid round-robin {
    	 { .backend = { .host = "127.0.0.1"; .port = "3131"; } }
    }
    
    director dnsdir dns {
    	 .list = {
    	       "201.7.184.0"/32;
    	 }
    }
    
    sub vcl_recv {
        set req.backend = dnsdir;
    }
    
    Fixes #1295
