Set the child pid to -1 after we've waited for it and take care to
avoid killing pid -1.  This makes it a bit more explicit and removes
the need for a separate variable to track the child's status.
Sudo already stops processing signals after it receives SIGCHLD so
it is not vulnerable to CVE-2017-2616.
