Fix an error to prevent some core dumps from ps.
You can get ps easily to core dump, if you are running a "make depend"
on a kernel in one window and a "ps -auxww" in another. The ww will
try to give you the full argument list of the command that can
now be 64Kb large, but ps expected only 4Kb large arg arrays and
doesn't check for overflows.
