Subject: [PATCH] fix example in graceful-shutdown.md: add `drop(listener)`

Need to drop the listener for the graceful shutdown to fully succeed. Otherwise, even though we cannot `curl` the server addr, `netstat` still shows the process listening. This will align the example with the hyper-util example in:
https://github.com/hyperium/hyper-util/blob/e74ab7888638e768de17c47ed5f20c8b623a308f/examples/server_graceful.rs#L47
