Pawel Jakub Dawidek 9cdb62160b Fix information leakage. 
Without this fix it is possible to cheat policies like:
- sysctl security.bsd.see_other_[gu]ids=0,
- mac_seeotheruids(4),
- jail(2)
and get full processes list with their arguments.

This problem exists from revision 1.62 of kern_proc.c when it was
introduced.
