    build: Use gnome.post_install() and install_symlink()
    
    The custom install script still depended on GTK 3.
    Instead of updating it, let’s just use Meson’s purpose-built functions.
    
    The FIXME in the install script was already resolved by
    https://gitlab.gnome.org/GNOME/gnome-maps/commit/7ed2ff45342bda73244c7675677ab1d63e4527eb
    
    Also let’s run `update-desktop-database` since we install a desktop file.
    
    This requires Meson 0.59 for `post_install`’s `update_desktop_database` kwarg,
    and Meson 0.61 for `install_symlink`.
