rcutorture: Enable RCU priority boosting for TREE09
The TREE09 rcutorture scenario exhausts memory from time to time, and
this is due to a reader being preempted and blocking grace periods,
thus preventing recycling of the memory used in callback-flooding tests.
This commit therefore enables RCU priority boosting and sets the boosting
delay to 100 milliseconds after grace-period start.
