Enhance localedef --list-archive option.
The localedef --list-archive option claims that it can accept a [file] argument and list the contents of that archive. The support was never implemented. This patch adds that support and allows --list-archive to work as expected. You can now use localedef to list the contents of arbitrary locale archives by using: ./localedef --list-archive file
