Context

I launched some test release pipelines and they failed. This MR fixes the release pipeline. To do that:

it introduces new stages to only start jobs that require artefacts from other jobs when those other jobs have finished (I think it actually worked without this fix though);
it fixes the gitlab-take-ownership target of the Makefile (the chown is needed for static executables to have the right --version).

Manually testing the MR

Those were pipelines done on MR !6323 (merged) which adds job opam:release which still failed in https://gitlab.com/tezos/tezos/-/pipelines/644073690 but you can see that the gitlab:release job was fixed.
