Fix lineinfile Ansible template emitting empty regexp

[HSP18SCM23P]

Description:

The shared lineinfile template was the only ansible_lineinfile call site omitting the regex argument, so every generated task shipped regexp: '' which matches every line and causes Ansible to replace the last line of the target file (destroying it on first run, appending duplicates after). The fix passes an explicit anchored regex per rule.

Fixes #15034

Hi @HSP18SCM23P. Thanks for your PR.

I'm waiting for a ComplianceAsCode member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Note: set_firewalld_default_zone and sssd_enable_certmap are intentionally untouched — both rules disable the ansible and bash backends, so the lineinfile template is never rendered for them.

Please make sure all those extra empty newlines are not part of the proposed changes.

Confirmed — the extra blank lines have been removed. The diff is now exactly the five one-line regex: additions plus the template fix (+6/−3 across 6 files), pushed in cleanup commits 952478f–ae615bc.
