[Toybox] ps

[enh]

ps seems pretty broken by the recent changes:

$ ./toybox_unstripped ps -o cmd,cmdline,comm -A
...
[/3:0 er/3:0]               [/3:0 er/3:0]               /3:0 er/3:0
[/37:0 r/37:0]              [/37:0 r/37:0]              /37:0 r/37:0
[/41:0 r/41:0]              [/41:0 r/41:0]              /41:0 r/41:0
[/25:2 r/25:2]              [/25:2 r/25:2]              /25:2 r/25:2
[/6:0 er/6:0]               [/6:0 er/6:0]               /6:0 er/6:0
...

these are kworker threads, as an obviously broken example. the
equivlent ps output (minus the android/toybox cmdline extension) looks
like this:

[kworker/3:0]               kworker/3:0
[kworker/37:0]              kworker/37:0
[kworker/41:0]              kworker/41:0
[kworker/25:2]              kworker/25:2
[kworker/6:0]               kworker/6:0
