Make sure that PATH exists or it will not work

This will fix problem on certain systems where cron does not export
basic PATH. So, cron will not update IPs because iptables is not
in PATH. For example:

/opt/netflix-proxy/scripts/ddns_updater.sh: line 30: iptables: command not found
/opt/netflix-proxy/scripts/ddns_updater.sh: line 30: iptables-save: command not found
