libnet: Remove unused cmd/readme_test

This command was originally added by https://github.com/moby/libnetwork/commit/ea7f555446401de09fc2410aba691bf70bbb2dee
to test the code snippet put into libnet's README.md. Nothing compiles
this file and it doesn't add any value to the project. So better remove
it than maintaining it.

This commit also removes the code snippet from libnet's README.md for
the same reasons.

 There are many networking solutions available to suit a broad range of use-cases. libnetwork uses a driver / plugin model to support all of these solutions while abstracting the complexity of the driver implementations by exposing a simple and consistent Network Model to users.
