Fix unminimize to correctly list packages (LP: #1996489)

Prior to dpkg/1.21.0, there was a bug where dpkg -V/--verify
couldn't list all the correct packages correctly but with
that being fix and in archive since Jammy, this works perfectly
but the syntax to report the missing files have changed. It
just prints 'missing' now. With that new format, we can now
fix the regex to simply list the packages.

With this patch, the unminimize script works flawlessly
on a minimized image.
