sched/debug: Provide slice length for fair tasks
[ Upstream commit 9065ce69754dece78606c8bbb3821449272e56bf ]
Since commit:
857b158dc5e8 ("sched/eevdf: Use sched_attr::sched_runtime to set request/slice suggestion")
... we have the userspace per-task tunable slice length, which is
a key parameter that is otherwise difficult to obtain, so provide
it in /proc/$PID/sched.
[ mingo: Clarified the changelog. ]
