rcutorture: Test partial nohz_full= configuration
The current set of tests covers only cases where either all possible CPUs are nohz_full= CPUs or none of them are. Because there have been some recent bug escapes in cases where only some of the CPUs are nohz_full= CPUs, this commit add a configuration where only half of the CPUs are nohz_full= CPUs.
