rcutorture: Handle different mpstat versions
The mpstat command recently added the %gnice column, which messes up the cpu2use.sh script's idle-CPU calculations. This commit therefore uses $NF instead of $12 to select the last (%idle) column. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
