* Run no-unwanted-files sanity test only on Ansible.
Since collections should be able to use binary modules there is not really any limit on what could exist in a collection `plugins` directory.
* Add support for symlinks in sanity target lists:
- Sanity tests that need to analyze symlinks can do so using the supplied target list.
- Tests that analyze directories will now only look at symlinks if requested.
- Directory symlinks will now be seen as directories instead of files.
* Enable symlinks on filename based sanity tests.
Sanity tests that evalulate filenames instead of content should include symlinks.
* Update symlinks sanity test.
Use the sanity test target list now that it can include symlinks.
