    libnet_join: use sitename if it was set by pre-join detection
    
    When domain member is joined to AD, we need to use the same DC to
    authenticate against after the join because the machine account might
    not be replicated yet to other domain controllers, including off-site.
    
    Bug https://bugzilla.samba.org/show_bug.cgi?id=11769 dealt with
    detection of the site pre-join. However, we rewrite private local
    krb5.conf afterwards without taking the discovered site name into
    account.
    
    Fix this by reusing the site discovered pre-join.
