[crypto] Fail fast if cross-certificate source is empty
In fully self-contained deployments it may be desirable to build iPXE
with an empty CROSSCERT source to avoid talking to external services.
Add an explicit check for this case and make validator_start_download
fail immediately if the base URI is empty.
