Updates for the unarchive module and action_plugin.

There is a bit going on with the changes here. Most of the changes are cleanup of files so that they line up with the standard files.

PR #5136 was merged into the current devel and brought up to working order. A few bug fixes had to be done to get the code to test correctly. Thanks out to @pib!

Issue #5431 was not able to be confirmed as it behaved as expected with a sudo user.

Tests were added via a playbook with archive files to verify functionality.

All tests fire clean including custom playbooks across multiple linux and solaris systems.
