s3:smbcacls: Add support for DFS path

smbcacls does not handle DFS paths correctly. This is beacuse once the
command encounters a path which returns STATUS_PATH_NOT_COVERED, it does
not attempt a GET REFERRAL.

We use cli_resolve_path API to perform a DFS path resolution to solve
the above problem.

Additionally this removes the known fail against smbcacls tests
