Fix: cib: Broadcasts of cib changes should always pass ACLs check
    
    Previously in cib legacy mode, if a cib change was requested by an
    unprivileged user that had limited permissions to the cib, after it got
    accepted by the master cib daemon, the broadcast of the cib change would
    get denied by the ACLs check of the slave cib daemons since the user
    didn't have the permission to write the additional bits from the
    broadcast such as the cib properties like "epoch", "num_updates" and so
    on.
    
    Technically, the broadcast of a cib change is issued by the master cib
    daemon as CRM_DAEMON_USER instead of the user that originally requested
    the change. The broadcast should always pass the ACLs check when it's
    processed by the slave cib daemons.
    
    This commit fixes the issue by overwriting any existing F_CIB_USER field
    in a broadcast with the privileged user CRM_DAEMON_USER.
