CIS 2.2.1.2 compliance

CIS 2.2.1.2 requres a specific flags to be set by default.

These flags are the following:

  restrict -4 default kod nomodify notrap nopeer noquery
  restrict -6 default kod nomodify notrap nopeer noquery

The -4 in the first line is optional and options after default can
appear in any order. Additional restriction lines may exist.

This request makes ntp.conf configuration compliant with CIS 2.2.1.2
