    Clean up horizon httpd pid files for RPM distros

    (apply same fix that we did for keystone, to horizon)

    In some cases we're seeing httpd not cleaning up properly after itself,
    which results in the horizon container failing to restart. This is
    confirmed to happen on rpm based distros, but have not had any reports
    on Ubuntu.
