The following commit fixes BZ: #1101669.
    
    Changes:
    
    - Install the mk-job binary on /usr/bin.
    - Make sure the proper permissions are given to /var/lib/check_mk_agent/job
      to prevent any hard or symlink to be created by a normal user and pointing
      to any file on the filesystem exposing it on the check-mk-agent output being
      run as root.
