ci: move the "tempory work dir" to "concurrency-safe" location

Lets not use a global location and move at the root of the directory dedicated
to the job.

 # Don't run pipelines on branch "merge", since we're fast-forward only.
 # Gitlab sees a new branch (since e.g. `topic/stable/my-topic` becomes
 # `branch/stable`), but the hash hasn't changed. There is no reason to
 # re-run the CI in our case, since we haven't built up any specific automation.
 # Right now it's just wasted CI and developer time.
 # One can still run the pipeline manually via the web interface,
 # like in the case of releases, to make *extra* sure that the actual branch
 # has succeeded.
