Update prepare_setWorkplace.sh file.
    
    - Previously, the option provided to verify the existence of symbolic
      links was incorrect. This make tcar to fail symbolic link
      verification. This update changes prepare_setWorkplace.sh to fix the
      option passed to verify the existence of symbolic links.
    
    - Previously, no message was printed before the confirmation question
      related to rendering images for branding other images. This was
      because no option was set describing the way the message would be
      printed out. This update changes prepare_setWorkplace.sh file to add
      the option that describes the way the message should be printed out.
