    pwait tests: Fix some exit annotations
    
    A number of tests rely on timeout(1) to kill a pwait instance, and with
    --preserve-status the corresponding exit status is propagated to
    atf_check.  Update the checks to reflect this.
    
    MFC after:      2 weeks
    
    (cherry picked from commit 987ef153c28878c3968420663f6061d6e70540a8)
