[virt-tools-list] [libosinfo PATCHv3 6/9] loader: Read media language information

[Christophe Fergeau]

Getting language information can either be supplied through a
series of <l10n-language> tag set on the <media> element or through
a regex that will be applied on the media volume ID.
The former should be all that is needed for most Linux distros while
the latter will be useful to get the language of Windows images.
