I don't think it really matters to a debugger why exactly a request
failed.  A human user might be able to take different action on an
ordinary 404 (buildid is just not indexed) vs.  other things that
indicate system configuration or connectivity problems, but I wouldn't
bother try to pass maximum curl/http fidelity back through mere errno
codes.  

Maybe for purposes of smarter clients, we could extent the
debuginfod_client object with the curl return code, and then have
debuginfod-find print that too.
