Handle duplicate keys on GPG key ring (#17242)
It is possible that a keyring can contain duplicate keys on a keyring due to jpegs or other layers. This currently leads to a confusing error for the user - where we report a duplicate key insertion. This PR simply coalesces keys into one key if there are duplicates. Signed-off-by: Andrew Thornton <art27@cantab.net> Co-authored-by: 6543 <6543@obermui.de>
