Process: Fix PID & UID column widths off-by-one error 

If the max PID or UID value for a platform is exactly a power of ten
(10000, 100000, etc.) the column widths of PID and UID would be 1 char
less than the correct number of digits. This is caused by the wrong
rounding function (ceil(x)); change to the correct one (trunc(x) + 1).
