When the per-node external_http_url feature was introduced by c197a2d8b24e2fa4c5e7901e448da1b0c93fcd26, it only applied to a config floppy. This fix ensures that it is also used for the boot ISO, both when it is generated locally (by _prepare_iso_image()) or just cached locally (by prepare_remote_image()).
