sched/debug: Print each field value left-aligned in sched_show_task()

Currently, the values of some fields are printed right-aligned, causing
the field value to be next to the next field name rather than next to its
own field name. So print each field value left-aligned, to make it more
readable.

Before:
stack: 0 pid: 307 ppid: 2 flags:0x00000008
After:
stack:0 pid:308 ppid:2 flags:0x0000000a

This also makes them print in the same style as the other two fields:

task:demo0 state:R running task
