deckard.py: start the server without `start_new_session`

This hopefully prevents the daemons from hanging after ^C exit.

subprocess.Popen is now run without the start_new_session=True parameter.

According to the docs this doesn't call setsid() before forking. But I'm not sure about what other implications this change might have.

Closes: #3 (closed)
