rcutorture: Default grace period to three minutes, allow override

Browse Source 
The default test grace period of two minutes is insufficient in some
cases and excessive in others.  This commit therefore increases the
default to three minutes, but also adds a --shutdown-grace parameter
to allow the default to be overridden.
