[PATCH resend v2] sched/debug: fix trival print task format

[Xie XiuQi]

Ensure leave one space between state and task name.

w/o patch:
runnable tasks:
 S           task   PID         tree-key  switches  prio     wait
-----------------------------------------------------------------
 I    kworker/0:2   656     87693.884557      8255   120
 Sirq/10-ACPI:Ged   829         0.000000         3    49
 Sirq/11-ACPI:Ged   830         0.000000         3    49
 Sirq/50-arm-smmu   945         0.000000         3    49

with patch:
runnable tasks:
 S            task   PID         tree-key  switches  prio     wait
------------------------------------------------------------------
 I     kworker/0:2   656     87693.884557      8255   120
 S irq/10-ACPI:Ged   829         0.000000         3    49
 S irq/11-ACPI:Ged   830         0.000000         3    49
 S irq/50-arm-smmu   945         0.000000         3    49

v2:
 - fix a typo
 - simpler to add one space before print format
