Fix CIS 2.2.1.2

Nessus requires that 'restrict' lines contain arguments in a specific order.

Non-compliant file(s)
---------------------
/etc/ntp.conf - regex '^[\s]*restrict[\s]+-4[\s][^:]' found
expect '^[\s]*restrict[\s]+-4[\s]+default[\s]+kod[\s]+nomodify[\s]+notrap[\s]+nopeer[\s]+noquery[\s]*$' not found in the following lines:
  15: restrict -4 default kod notrap nomodify nopeer noquery

Solution
--------
Add or edit restrict lines in /etc/ntp.conf to match the following:
  restrict -4 default kod nomodify notrap nopeer noquery
  restrict -6 default kod nomodify notrap nopeer noquery
