Update cli_getLocales.sh:
    
        - Add `pt_PT' as valid locale for centos-art.sh script. Since we
          are using LL_CC format for Portuguese language, we cannot use
          just LL format for pt, so we need to distinguish pt languages
          using LL_CC. 
          
          Remainder: When we use LL_CC format for a language, there is
          no possible change to use LL format only for that language.  The
          language format evaluation takes place using the most
          descriptive definition first and the less descriptive definition
          last (i.e., `LL_CC.ENCONDING', `LL_CC' and `LL').  The first
          format that match (in that order) is used.
