rcu: make RCU_BOOST default on RT
Since it is no longer invoked from the softirq people run into OOM more often if the priority of the RCU thread is too low. Making boosting default on RT should help in those case and it can be switched off if someone knows better.

This option boosts the priority of preempted RCU readers that
block the current preemptible RCU grace period for too long.
