shutdown: prevent core dumps in final shutdown stage

If the system is finally shutting down it makes no sense to write core
dumps as the last remaining processes are terminated / killed. This is
especially significant in case of a "force reboot" where all processes
are hit concurrently with a SIGTERM and no orderly shutdown of
processes takes place.
