    Revert "source4/scripting: add an option to samba_dnsupdate to add ns records."
    
    This reverts a totally unnecessary change to samba_dnsupdate. The self test
    environment does the correct things with NS records now.
    
    This reverts commit af08cb2eee9dc9fabad6ca62ca11728209297222.
