bug#32026: [PATCH v4 1/9] gnu: Add a 'update-mozilla-locales' helper for maintenance.

[Ludovic Courtès]

Hey Maxim,

Thanks a lot for working on this!  Having locales available makes a big
difference to many users.

(A couple of years ago I started working on that for the LibreOffice
package.  I got quite far but didn’t complete it.  I can dig that from
my stashes if there’s interest in giving a hand.)
