2.2.1.2 ntp conf test looks for wrong config filename

[rabcin]

It checks for /etc/ntpd.conf and should be /etc/ntp.conf

[rabcin]

also some issues on the checks as then look for different configuration to that recommend in the CIS benchmark.

    grep "^restrict -4 **default** kod nomodify notrap nopeer noquery" /etc/ntp**d**.conf &>/dev/null || state=1
    grep "^restrict -6 **default** kod nomodify notrap nopeer noquery" /etc/ntp**d**.conf &>/dev/null || state=2
    egrep "^(server|pool) .*$" /etc/ntp**d**.conf &>/dev/null || state=4

missing the word "default" compare with the CIS guide, also for config file under /etc should be ntp.conf (without 'd')
