initscripts: redirect systemctl status output
    
    When running locally, the systemctl pager can come up
    in some circumstances, preventing the test run from
    continuing because it is waiting for stdin.
    
    The redirect prevents this from happening, and will
    output only in case of error for troubleshooting.
