Update centos-art.sh scripts.
    
    - Previously, the tcar_getTemporalFile was using one variable
      expansion for RANDOM variable in from of temporal files. This update
      changes the tcar_getTemporalFile to strength the random number set
      in front temporal files by adding anoterh RANDOM variable expansion
      after the one already existent. Now the random number is twice
      larger and more difficult duplicate.
    
    - Previously, the tcar_setTranslationMarker function wasn't expanded
      any translation marker related to release numbers. This update
      changes tcar_setTranslationMarker to add both =RELEASE= and
      =MAJOR_RELEASE= markers. These markers are expanded based on the
      value of RELEASE and MAJOR_RELEASE variables, respectively.
