Subject: [PATCH] winbind idmap plugin: update struct idmap_domain to latest
 version

While updating to interface version 6 we forgot to add the query_user
member.

Recent version of Samba added a new member dom_sid. Unfortunately the
interface version was not update for this change so we have to enable
the member based on the Samba version.
