Update pass aging rules to not ignore empty pass

[Xeicker]

Description:

• Update regex in accounts_password_set_max_life_existing & accounts_password_set_min_life_existing so empty passwords are not ignored

Rationale:

• Empty string can be a password and should be treated the same as any other

Review Hints:

• The introduced tests should cover this new behavior

Hi @Xeicker. 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.
