Subject: [PATCH] Fix tabelating output in (skopeo inspect --format)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

tabwriter buffers lines that contain \t in memory, and only
writes them out on a .Flush(). So actually call that.

Without this, things like
> --format 'name\tdigest\tlabels\n{{.Name}}\t{{.Digest}}\t{{.Labels}}\n'
result in no output at all.
