hyperstart: Don't special-case destroypod

We're supposed to be able to receive an ack message after a destroypod.
The fact that we didn't was caused by our use of hyperstart as a daemon
(vs an init process) and some bugs introduced by that.

With those fixed, we have the destroypod ack message back.
