[json-glib] build: Use Meson's i18n 'glib' preset

[Emmanuele Bassi <ebassi src gnome org>]

commit 1a0eeb7db59589fe56893b0836f406d723f8553c
Author: Emmanuele Bassi <ebassi gnome org>

    build: Use Meson's i18n 'glib' preset
    
    We should simplify the localisation build by using the 'glib' preset
    provided by the Meson i18n module. This includes:
    
     - getting the list of localisations from the po/LINGUAS file
     - a full list of translatable keywords and flags
    
    Which means we can drop almost all content from the po/meson.build file
    and just use the upstream settings.
