It shouldn't just warn, it should error out if archivefetch does not
succeed in fetching an archive. And that works fine when using -b with a
default prefix, at least.

But we do appear to be assuming in a couple of places that if you are
using binary-only mode then you will have at least one usable entry in
archive_sites; archivefetch_main for example where all_archive_files
will be empty if there are no archive_sites.

So while this configuration should not be expected to work, we should
error out instead of continuing. r119938
