In one round of compilation I saw more than 20 packages failing due to this
missing shadow-utils dependency so several changes might be required.

Let me add some other packages are failing due to another missing dependency:
rpm-build. 

Only 2 for now so far seen in my setup.

Agree! Since we are reusing this mock environment, I am in favor to add via
modify-build-cfg.
