taskset: fix for PID longer than 12 chars

Should we validate that PID is a number for "taskset -ap PID"?
We don't actually need it, and pathological input like
"../../DIR_WITH_LOTS_OF_PIDS" can only cause "taskset"ing
of many pids. Which is something user can do anyway.

function                                             old     new   delta
taskset_main                                         190     181      -9
