[Mimedefang] Mimedefang sometime doesn't timeout Mail::SpamAssassin::Timeout parts in SA plugins

Hi,

I suspect SA itself has the same problem but since I did only some tests the
problem never happened to me.

The same problems.

Yes the example was a bad one since I'm working in my plugin completly
with pipes so I should have made one with pipes too.

I've changed SIGTERM now to be SIGKILL, let's see it that helps.
