[Samba] ACLs for users with no permissions

[Tom Dickson]

Would it be possible to add a

suppress empty permissions = yes

option that would cause Samba to not send an ACL group if the group has 0
UNIX permissions.

For example; if a file has rwx------, then samba could return only the owner
in the Windows Security dialog for the file. Right now it will return the
group and "Everyone", both with no permissions, which is confusing to
Windows administrators.
