Handle additional server options in ntp.conf
Handle additional server options in ntp.conf

ntpd allows additional options on the server line, for example,
server ntp.example.com iburst
is a valid server line in /etc/ntp.conf. However, the previous code
would set the ntp server as "ntp.example.com iburst" which could not
be resolved

Changed the code to strip off anything on the server line after
the hostname or IP address
