Subject: [PATCH] daemon/parsePsOutput: minor optimisation

It does not make sense to keep looking for PID once
we found it, so let's give it a break.

The side effect of this patch is, if there's more than one column
titled "PID", the last (rightmost) column was used before, and now
the first (leftmost) column is used. Should make no practical
difference whatsoever.
