Fix knote handling for exiting processes: when triggering a NOTE_EXIT
knote, remove it from the process's klist; after handling those,
remove and drop any remaining knotes from the process's klist. Ban
attaching knotes to processes that have started exiting or attaching
them via the pid of a thread other than the main thread.
