Add separate build process for node test.

This PR is part of https://github.com/kubernetes/kubernetes/pull/31093. However, because currently node e2e is built on `KUBE_TEST_PLATFORMS`, which includes linux/amd64, darwin/amd64, windows/amd64 and linux/arm, it caused #32251 to fail.

In fact, node e2e is running on the same node with kubelet, and it also has built-in apiserver, etcd and namespace controller. All of them are only built on `KUBE_SERVER_PLATFORMS`, so node e2e should also only be built on those platforms.
```
KUBE_SERVER_PLATFORMS=(
     linux/amd64
     linux/arm
     linux/arm64
   )
```

This PR added a separate build process for node e2e to address this.

@vishh Do you need this for v1.4? because this blocks your #32251. /cc @dchen1107
