fix: ansible build_profile_remediations: add and use remove_too_many_…

…blank_lines

Without this ansible-playbook-per-profile-yamllint-check tests fail as
between rule segments there can be extra lines because of some reason.

Like:
./fedora-playbook-standard.yml
  342:1     warning  too many blank lines (5 > 2)  (empty-lines)
  1124:1    warning  too many blank lines (3 > 2)  (empty-lines)
...
