[BusyBox] Small and tiny ps_main.c modification

[Christophe Boyanique]

Here is a ridiculous patch to ps_main.c to harmonize options parsing error
with the 2 ps versions (with or without kernel devps patch).

Why am I bothering with that ? Because I'm preparing a new version for my
patch to add (optional) parameters to ps.

Christophe.
