Allow debugfs override of sched_tick_max_deferment in order to ease finding/fixing the remaining issues with full nohz.

The value to be written is in jiffies, and -1 means the max deferment is disabled (scheduler_tick_max_deferment() returns KTIME_MAX.)

This is just an attempt to revive and hopefully finalize the discussion started a while back[1].
