rcu: Update rcutorture defaults 

A number of new features have been added to rcutorture over the years, but
the defaults have not been updated to include them.  This commit therefore
turns on a couple of them that have proven helpful and trustworthy, namely
periodic progress reports and testing of NO_HZ.
