    route: fix `route -n monitor` when its output is redirected

    This is a small oversight in the transition to netlink; the non-netlink
    implementation would explicitly flush its stdout as necessary to avoid
    apparent long stalls in output when we end up fully-buffered.  Adjust
    the netlink implementation to do the same.  This was noticed while
    trying to triage failures in the wg-quick script.
