[PATCH 5/6] tar: Avoid acl_ prefixes for functions

[Adolf Belka <adolf.belka@ipfire.org>]

- The latest updates for acl and attr created some functions that ended up duplicating
   ones that tar had created. This patch has been implemented to make these functions
   start with tar_ so that they are specific to the tar project.
- No change to the rootfile
