Fix find to work with xargs -0

[alanmcanonical]

Description:

• Fix find to work with xargs -0
• Follow symlink in ansible

Rationale:

• The bash remediation mis-parses the interface list when more than one wireless interface is present, because it pipes newline-separated find output into xargs -0.
• The paths defined there are symlinks

Hi @alanmcanonical. 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.

Tip

We noticed you've done this a few times! Consider joining the org to skip this step and gain /lgtm and other bot rights. We recommend asking approvers on your previous PRs to sponsor you.

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.
