proxy/iptables: don't proxy ExternalName services

Browse Source 
The API docs say:

	// ServiceTypeExternalName means a service consists of only a reference to
	// an external name that kubedns or equivalent will return as a CNAME
	// record, with no exposing or proxying of any pods involved.

which implies that ExternalName services should be ignored for proxy
purposes.
