Modifications to osaSocket::GetLocalhostIP()
 * Use the first address in the AF_INET family (previous behavior was to only look at the first value returned by getifaddrs() and return an empty string if its family did not match AF_INET)
 * Removed the return 0 so that an empty string is returned instead; this would actually cause a crash
