[Rico Tzschichholz <ricotz src gnome org>]

commit 84f15fabf505e330710f867fa3d1e9f4fdae30bf
Author: Rico Tzschichholz <ricotz ubuntu com>

    json-glib-1.0: Change abstract methods of Serializable to virtual
    
    All those interface methods have default implementations. Additionally drop
    superfluous metadata.
    
    Fixes https://gitlab.gnome.org/GNOME/vala/issues/840
