Add url for swupd in builder.conf

The update client currently defaults to the public clearlinux url, and must be
overridden with cmd line options to use other version/content/format urls. This
introduces a problem when running a mix, and not supplying the mix URL will
cause swupd to update from the official URL, rather than the mixer url.
With this patch, the URLs can all be specified and are inserted into conf files
that the swupd client will read, to know what URL to default to.
