libsepol: fix neverallow checking on attributes

Ole Kliemann reported that allow rules written using type attributes were
not being detected by neverallow assertions in the policy.  I think that
this was broken in policy.24 and later due to changes in the type datum.
Fix the expand logic to correctly distinguish type attributes from types.
