GetSystemIps doesn't report every available ips in Dockerized wings

[RMartinOscar]

Because it gets them from the net package instead of from host/docker

wings/system/system.go

Lines 156 to 169 in de4ea00

	func GetSystemIps() (*IpAddresses, error) {
	var ip_addrs []string
	iface_addrs, err := net.InterfaceAddrs()
	if err != nil {
	return nil, err
	}
	for _, addr := range iface_addrs {

	if valid && !ipNet.IP.IsLoopback() {
	ip_addrs = append(ip_addrs, ipNet.IP.String())
