[virt-tools-list] [libosinfo v3] install-scripts: Translate lang format when needed

[Fabiano Fidêncio]

Add this translation in the windows template file because the script
must have the language set using non-linux standard format.
Windows will use, for instance, en-US instead of en_US or en_US.utf8.
