Discourse: build libvips 8.18 for its image worker

Discourse enabled libvips image processing by default and its worker refuses anything older than 8.18; Debian 13 ships 8.16, so the service failed to boot after an update and on fresh installs. Build the latest libvips release from source like discourse_docker does, on install and on update when a new release is out.
