Subject: [PATCH] launch_daemon: Trigger sticky-already-triggered external
 events immediately.

If the external event is sticky and already triggered, then we want
to trigger any newly-added events immediately. This fixes "boot hangs
on rocket" regressions following 4f126f690c17de00f44135f46acf0664ede61ab1,
which seems to have exacerbated this already-existing race condition.

Fixes #17289.
