[Exim] Small change to exiwhat

Hi,

the current "ps xau | egrep" solution is too slow for exim, i changed it
a little bit, so it works with all those fast exim-processes. With
killall it does not complain about not existing PID's anymore (at least
on my system, even on high load).

Apply this patch, if you want to try it.
