rcutorture: Add diagnostic for unscheduled system shutdown

Currently, rcutorture can terminate via rmmod, via self-shutdown,
via something else shutting the system down, or of course the usual
catastrophic termination. The first two get flagged, so this commit adds
a message for the third. For the fourth, your warranty is void as always.
