rcu: fix rcutorture behavior during reboot

Impact: fix very rare reboot hang

Because rcutorture ignored all signals, it does not terminate in
response to the signals sent at shutdown time.  This can cause strange
failures due to its continuing to make use of kernel function too late
in the shutdown sequence.  This patch therefore adds a shutdown notifier
to rcutorture, causing it to shut down in response to a reboot or an
orderly shutdown.
