    build: Use the post_install method
    
    At the moment, eog uses a custom install script to compile schemas
    and update icon cache. However, since meson 0.57 a new method exists
    in GNOME module to handle this tasks[0].
    
    The custom script has been removed to use the `post_install` method.
