CI: minor cleanup of some changesets

What

This is a minor MR addressing aimed to reduce the number of job we run on the CI automatically.

• The first commit adds a changeset to the job job_build_layer1_profiling : this job was unconstrained until now and always run
• The second commit removes two text files CHANGES.rst and LICENSES from the octez changeset : modifying these files do not modify the code and therefore is useless to run all the tests.
• The third commit fix a small bug in the rpm packages changeset.

Why

to reduce the number of jobs we run in the CI automatically.

How

Manually testing the MR

To test this MR you can just inspect the code and check if the changeset are correct. Maybe there is a better way creating a few test MR and check each commit in isolation, but I believe that for the nature of the MR this is not needed.
