    faillock: create tallydir before creating tallyfile
    
    The default tallydir is "/var/run/faillock", and this default
    tallydir may not exist.
    
    Function open may fail as tallydir does not exist when creating
    the tallyfile. Therefore, faillock will not work well.
    
    Fix this problem by creating tallydir before creating tallyfile
    when the tallydir does not exist.
