util: Fix terminate_processing() called from non-main thread

Browse source 
The current raise(SIGTERM) sends a signal to the calling thread. If
terminate_processing() is called from a non-main thread and that thread
was created at InitPostScript() time when SIGTERM is blocked, or has
blocked SIGTERM manually, terminate_processing() has no effect.

Switching to kill(getpid(), SIGTERM) guarantees that a thread that doesn't
block the signal (minimally the main thread) will run the handler.
