Improve reporting of error situations in find_other_exec().
This function suppressed any stderr output from the called program, which
is unnecessary in the normal case and unhelpful in error cases. It also
gave a rather opaque message along the lines of "fgets failure: Success"
in case the called program failed to return anything on stdout. Since
we've seen multiple reports of people not understanding what's wrong when
pg_ctl reports this, improve the message.
Back-patch to all active branches.
