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.
