rcutorture: Move common boot flags to kvm-test-1-rcu.sh
Currently, most boot flags are calculated in kvm-test-1-rcu.sh, except that rcutorture.test_no_idle_hz and rcutorture.verbose are set up by kvm.sh. This commit promotes one-stop shopping by consolidating the determination of boot flags into kvm-test-1-rcu.sh. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Reviewed-by: Josh Triplett <josh@joshtriplett.org>
