    build: Enable validation of the AppData file
    
    Add a build-time dependency on appdata-tools to enable validation of the
    AppData file during `make check`. See:
    https://github.com/hughsie/appdata-tools.
    
    This also requires an up-to-date version of gnome-common to pull in the
    appdata-xml.m4 macros.
