Eric van Gyzen 0e3d6ed44e kqueue EVFILT_PROC: avoid collision between NOTE_CHILD and NOTE_EXIT ...

NOTE_CHILD and NOTE_EXIT return something in kevent.data: the parent
pid (ppid) for NOTE_CHILD and the exit status for NOTE_EXIT.
Do not let the two events be combined, since one would overwrite
the other's data.
