Babel: Send out low-interval hello on shutdown
When shutting down a Babel instance we send a wildcard retraction to make sure all peers can quickly switch to other route origins. Add another small optimisation borrowed from babeld: sending a Hello message (along with the retraction) with a very low interval. This will cause neighbours to modify their expiry timers for the node's state to quickly time it out, thus conserving resources in the network.
