Make CheckAWSAuth, UploadToS3, ImportSnapshot, and RegisterAMI public so
a build server can run them individually (e.g. Marketplace publishing
after RegisterAMI). Rename BuildAMI to BuildAndImportAMI, now a thin
orchestrator over them. Each step records into Result and returns its
artifact; the AWS steps guard on their predecessor and error clearly if
called out of order.
