piuparts: Only depend on latest version

It may happen that the Packages files contain multiple versions of a
package. Using `apt-cache show` list all of them leading to the
situation, where the generated "piuparts-depends-dummy" has multiple
dependencies on the same package with different versions:

  Depends: pkg (= 1), pkg (= 2)

Use `apt-cache show --no-all-versions` to only lists the version with
the highest priority.
