[Libguestfs] [v2v PATCH 02/14] po-docs: turn language list into LINGUAS file

[Pino Toscano]

Use a LINGUAS file with the list of available translations instead of
defining them in a make variable. This way Weblate will be able to
update the list using an available addon, and we do not need to list
those not built.

Accordingly, rename the variable with built languages to
'linguas_translated'.
