fixed: win_copy failure from a VirtualBox share to a local path

In the case when a source file/folder is on a VirtualBox share then
win_copy task fails.
E.g.
  - name: Copy file from VirtualBox share
    win_copy:
      src: \\vboxsvr\share\file
      dest: c:\local\path
      remote_src: true

The reason is that .GetAccessControl method fails somehow for a
file/folder on a VirtualBox share.

  PS c:\Users\vboxuser> $file = Get-Item -Path \\vboxsvr\share\file
  PS c:\Users\vboxuser> $file.GetAccessControl();
  Exception calling "GetAccessControl" with "0" argument(s): "Method
  failed with unexpected error code 1."
  ...

So, remove the ACL stuff
