Subject: [PATCH 1/3] sched:Properly format runnable tasks in /proc/sched_debug

With !CONFIG_SCHEDSTATS, runnable tasks in /proc/sched_debug has too
many columns than required. Fix this by printing appropriate columns.

While at this, print sum_exec_runtime, since this information is
available even in !CONFIG_SCHEDSTATS case.
