procutil: make recent fix for zombies compatible with py2
The fix in
ed684a82e29b (procutil: always waiting on child processes
to prevent zombies with 'hg serve', 2020-05-07) works only on Python 3
because it passes a `daemon` argument to `threading.Thread()`. Python
2 requires you to assign to the `.daemon` property instead. Python 3
also seems to support that, so this patch fixes the code by
unconditionally using the old form.
