Kernel: Process::for_each_in_pgrp() should not include dead processes

Browse source 
We don't care about dead processes that were once members of a specific
process group.

This was causing us to try and send SIGINT to already-dead processes
when pressing Ctrl+C in a terminal whose pgrp they were once in.

Fixes #922.
