auto update: fix usage of --authfile

The --authfile flag has been ignored.  Fix that and add a test to make
sure we won't regress another time.  Requires a new --tls-verify flag
to actually test the code.

Also bump c/common since common/pull/1538 is required to correctly check
for updates.  Note that I had to use the go-mod-edit-replace trick on
c/common as c/buildah would otherwise be moved back to 1.30.

 For a container to send the READY message via SDNOTIFY it must be created with the `--sdnotify=container` option (see podman-run(1)).  The application running inside the container can then execute `systemd-notify --ready` when ready or use the sdnotify bindings of the specific programming language (e.g., sd_notify(3)).
