    build: Use GNOME module post_install()
    
    This greatly simplifies the post install script. As this functionality
    depends on newer meson (0.59.0) it is guarded by a version check.
    Distributions usually use their own tooling so it's does not matter if
    they don't run the postinstall scripts (e.g. because of using too old
    meson)
