[ekey] listen to udp6 instead of udp only

[hsteppke]

Expected Behavior

Taken the CV LAN Modul from ekey sends in ipv4 only the binding should listen to udpv4 sockets but it rather starts listen on udpv6 only.
I did verified it using "netstat -plunt" and there i see it only listen to the port i have given in the udp6 part only.

I suggest to change:
openhab1-addons/bundles/binding/org.openhab.binding.ekey/src/main/java/org/openhab/binding/ekey/internal/EKeyPacketReceiver.java
Line 82
try { // create socket
socket = new DatagramSocket(port);
} catch (SocketException e) {
e.printStackTrace();
}

Possible Solution

uses DatagramSocket(int port, InetAddress laddr) with a local IPv4 Addre

You're going to have to be a whole lot more clear. I have no clue what this is requesting.
