I made it so that CIFS_UNIX_EXTATTR_CAP indicates the availability of  
SMB_QUERY_FILE_UNIX_INFO2, since that was commented as indicating  
that chflags(2) was available. I'm not too fussed about this, but  
you're right that we should nail this down. IIRC George preferred  
having a separate capability for INFO2.
