Support downloading files, for instance via `podman load -i server.com/image.tar`. The specified URL is downloaded in the frontend and stored as a temp file that gets passed down to the backend. Also vendor in c/common@main to use the new `pkg/download`. Fixes: #11970 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
