[20.10] vendor: libnetwork c5aa85f9b25f0acaec8591ced679cb9fb5b9e32c

The commit used to build the docker-proxy binary is not updated as the
build script pulls from the public libnetwork repo but the
aforementioned commit only exists in a private fork until after the
security vulnerabilities being fixed have been publicly released. The
vulnerable code is not used in the proxy binary anyway.
