video: fix coverart decoding 

Deselecting cover art and then reselecting it did not work. The second
time the cover art picture is not displayed again. (This seems to break
every other month...)

The reason is commit 6640b22a. It mutates the input packet. And it is
correct that we don't own d_video->header->attached_picture at this
point. Fix it by creating a new packet reference.
