minor changes in debian packages files

What

This MR is part of a series of MR to add rpm packages to our CI.

The rpm files are built using the debian packages as source.

This MR in particular tackle a couple of inconsistencies in the debian packages to make it easier to build the rpm packages.

Why

How

I better specify the destination of binaries in the .install files

Remove a variable from the dependency docker file that can can infer from the version.sh file

generalize the build-packages-dependencies.sh to use any dockerfile.

Manually testing the MR

Make sure the pipelines for deb packages are green and it is still possible to build packages locally using make dpkg and scripts/packaging/build-deb-local.sh
