Cezar Sa Espinola e341bae08d net: use network and host as singleflight key during lookupIP 
In CL 120215 the cgo resolver was changed to have different logic based
on the network being queried. However, the singleflight cache key wasn't
updated to also include the network. This way it was possible for
concurrent queries to return the result for the wrong network.

This CL changes the key to include both network and host, fixing the
problem.

Fixes #30521
