windows: Set ReparsePoint Attribute in FileAttributes

The ReparsePoint Attribute is a primary attribute that is used
internally within the redirector to determine when the object
is a reparse point.  It must be set in all code paths that
obtain the FileAttributes from the service.  Do not fold it in
during the QueryBasicInformation response processing.
