sched/fair: enforce EAS mode
For non latency sensitive tasks the goal is to optimize for energy efficiency. Thus, we should try our best to avoid moving a task on a CPU which is then going to be marked as overutilized. Let's use the capacity_margin metric to verify if a candidate target CPU should be considered without risking to bail out of EAS mode.
