sched: Make use of sysctl_sched_wake_to_idle in select_best_cpu
sysctl_sched_wake_to_idle is a means to allow or disallow a global
task placement preference for idle CPUs. It has been unused thus
far since we've preferred to use a per-task flag instead to control
placement for individual tasks. Using this global flag, however, does
allow greater flexibility for testing and system evaluation.
Incorporate sysctl_sched_wake_to_idle in the placement policy.
