self-approval of uploads to -backports pocket

[Dan Streetman]

Hi Martin,

It seems you have been uploading the cockpit package to the backports
pocket for some releases, and then approving the upload yourself.

While you (clearly) still have technical access to approve uploads to
the backports pockets, the process has changed and you are no longer
on the backports team, and thus you should not be approving any
uploads to the backports pocket.

While we're happy to review any uploads you make to the backports
pocket, please don't approve any more uploads to backports; let your
uploads proceed through the normal process.

Thanks.
