getifaddrs fails in some linux environments - fix included

[asthomas]

I have a fairly complicated network interface set-up on my Linux machine, and not all of the network interfaces have IP addresses. The code in interfaces.py does not account for this possibility and therefore exaproxy fails to start. The fix is simple:

In function getifaddrs() in the file interfaces.py, there is a loop starting with

    while ifa:

After the while, add the following code:

        if ifa.ifa_addr == None:
            if ifa.ifa_next:
                ifa = ifaddrs.from_address(ifa.ifa_next)
                continue
            else:
                break
