container-toolbox: Fix typo between %pre and %post
    
    The snippet to fix the /run/lock breakage and the lines following it
    were copied from the first %post section in fedora-container-base.ks.
    However, the %end marker to terminate the previous %pre section, and the
    starting %post marker went missing in fedora-container-toolbox.ks
