    smbd: fix creation of BUILTIN\{Administrators,Users} when "tdbsam:map builtin = false"
    
    In this case, passdb/group mapping is not responsible for the id mapping
    of the builtins, so the check whether the SID maps to a unix ID is not
    valid for checking whether the builtin has been created as a proper group.
    So this patch changes the check to whether we find the builtin in the group
    mapping database.
