    ikev1: simplify "responding to Main Mode from unknown peer..." log lines
    
    Two log lines generate the message:
    
    - "responding to Main Mode from unknown peer THAT.HOST_ADDR:THAT.HOST_PORT"
    
      this would be logged if INSTANCE && HOST_PORT_SPECIFIC, but, based
      on the tests, this doesn't happen (the only test to even set
      HOST_PORT_SPECIFIC is ikev2-51-rw-nat-ikeport, and not with
      INSTANCE).
    
    - "responding to Main Mode from unknown peer THAT.HOST_ADDR on port MD.SENDER.PORT"
    
      this does happen, but why use THAT.HOST_ADDR to print the unknown
      peer when MD.SENDER has the value (I'm guessing history, I'm pretty
      sure the two are identical).
    
    The new log line looks like:
    
      "responding to Main Mode from unknown peer MD.SENDER"
    
    where MD.SENDER is correctly formatted using str_sanitize_endpoint().
    
    (when !INSTANCE, the even shorter message "resonding to Main Mode" is
    logged, wonder why that doesn't include "from peer MD.SENDER").
    
    Also; always debug-log the cookie, and debug-log HOST_PORT_SPECIFIC.
