While the mailer is normally opened/set if the mailto is set, this is not the case if the grandchild actually didn't produce any output. This change corrects the situation to only attempt to kill/close the mail process if it was actually opened in the first place. The reporter initially stumbled on the -n (suppress mail on success) flag leading to a SIGKILL of the process group, but simultaneously discovered/reported the behavior with !-n jobs if MAILTO was set and no output happened. All of these places that are checking mailto should actually be checking whether mail is set, so do that for consistency+correctness. This set of bugs were introduced by r352668.
