The issue is that for Samba, this is always overridden by waf.  The
value in this header is always wrong, we now always use
${SOCKET_DIR}/winbindd as the path.  

I don't like things being defined in two places, and this seemed the
better of the two paths to remove.  If this was an installed header, we
would pre-process the header to include the right path, but if it is a
public interface but intended to be copied out on an ad-hock basis,
removing the path from the definition seems the best option. 

What software uses our nsswitch/winbind_struct_protocol.h anyway?  My
memory was it had something to do with IBM.
