Specify job dependency to avoid unneeded artifacts

By default Gitlab will use the artifacts of all the previous stages,
causing the archive created at the pack stage to include unneeded
files. This creates confusion and increases the size of the tarball.

To overcome this issue, specify which are the artifacts we are interested.
