Remove netifaces lib reference

[awarecan]

Since 0.21.0, zeroconf replaced the usage of netifaces by ifaddr

Use zeroconf.interface_addresses to replace util.interface_addresses method. So that we can remove the depends of netifaces lib

fixes #214

Need help to test on real device supports SSDP protocol.
