Fix Ubuntu remediation for smartcard_pam_enabled

[mpurg]

Description:

• Fix Ubuntu remediation for rule smartcard_pam_enabled to correctly position pam_pkcs11 module in stack.

Rationale:

• The line auth [success=2 default=ignore] pam_pkcs11.so is incorrectly inserted at the bottom of the pam file instead of above pam_unix.so. Solution is to use another macro, which supports appending lines after a specific match.

Hi @mpurg. 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.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

@teacup-on-rockingchair could you check the error in the tests, it seems unrelated to the PR, but it would be good for you to confirm it.

The SLES issues seem unrelated to this PR and they should take a look on their side.
