[REGRESSION] kill segfaults w/ single, negative PID

[dann frazier]

[Impact]
The kill binary will segfault when called w/ a single, negative PID. This breaks a use case where you maybe sending the default signal (SIGTERM) to all processes (-1) or all processes in a process group (-<PGID). This is regression introduced via an SRU to fix LP: #1637026.

[Test Case]
$ /bin/kill -9
Segmentation fault (core dumped)

[Regression Risk]
This fix will now make our optparsing almost identical to current yakkety, for which I see no obvious regressions filed.
