Ian Jackson 5b1316f781 unix ExitStatus: Do not treat WIFSTOPPED as WIFSIGNALED
A unix wait status can contain, at least, exit statuses, termination
signals, and stop signals.

WTERMSIG is only valid if WIFSIGNALED.

https://pubs.opengroup.org/onlinepubs/9699919799/functions/wait.html

It will not be easy to experience this bug with `Command`, because
that doesn't pass WUNTRACED.  But you could make an ExitStatus
containing, say, a WIFSTOPPED, from a call to one of the libc wait
functions.

(In the WIFSTOPPED case, there is WSTOPSIG.  But a stop signal is
encoded differently to a termination signal, so WTERMSIG and WSTOPSIG
are by no means the same.)
