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.
