Subject: Dir.children is available since Feature #11302. FileUtils uses
 Dir.each on an internal method encapsulated on a private class
 `Entry_#entry`, having no '.' neither '..' entries would make now superfluous
 a chained reject filtering.

This change can improve the performance of these FileUtils
methods when the provided path covers thousands of files or
directories:

- chmod_R
- chown_R
- remove_entry
- remove_entry_secure
- rm_r
- remove_dir
- copy_entry
