Subject: kernel: shutdown when init quits

thanks to this it's easier to power off - instead of waiting for all
processses to quit (which now involves writing `quit` both on serial and
ps/2), one of those can just somehow kill init.

currently this is just done by exiting from any shell - init will return
from await and exit too
