Update locale module of centos-art.sh script.
- Previously, definition of PACKAGE_NAME and PACKAGE_VERSION variables
were set inside sh function. This update moves definition of these
variables from sh function to directory_getConfiguration function
which is higher in the module chain. Putting definition of these
variables at directory_getConfiguration function serves also to
other functions at the same level of sh, like svg and asciidoc that
need them too. With this update we avoid to duplicate definition of
PACKAGE_NAME and PACKAGE_VERSION variables in function files like,
sh, svg, and asciidoc when directory processing is performed.
