procutil: do not convert return code of signal exit to positive number (API)

The docstring states that "codes from kill are negative", and it doesn't
make sense to make exit/signal code ambiguous.

.. api::

   ``hook.hook()`` and ``hook.runhooks()`` may return a negative integer
   to denote that the process was killed by signal.
