hack: firecracker binary and CNI configuration

Add a target to the Makefile to download a version of firecracker and
extract it under the repository hack/firecracker. We will then use this
binary for running the VM.

Add a CNI configuration under hack/cni. This configuration will need to
be copied to `/etc/cni/conf.d`.
