gitlab-ci: fix message about files generated from owners.yaml

Crystal Wood pointed out that the current message about RHMAINTAINERS
and CODEOWNERS not matching owners.yaml is misleading. You need to first
build the tools before you can run them. The documentation correctly
says that you should run `make`. Update the error message.
