Avoid a failed/confusing re-upload by checking whether the package is already
published before PUTting it. artifactapi has no HEAD route (returns 405), so the
guard uses a GET against the served path (RPMs are stored under Packages/): a
200 means it exists and the upload is skipped, anything else proceeds.
Also point at the reachable artifactapi host (artifactapi.k8s.syd1.au.unkin.net,
as used by rpmbuilder) instead of the unresolvable artifactapi3 name.
