* fixes issue #386

* Correct typo

* Read kubernetes version from environment

Set kubernetes version to the value of the environment variable `KUBE_BENCH_VERSION` if it is defined and the flag `--version` is not specified on the kube-bench command line.

The command line flag `--version` takes precedence of the environment variable `KUBE_BENCH_VERSION` if both are defined.

* Add info about KUBE_BENCH_VERSION to README

Replace the `gt` with `eq` for string comparison of kube-bench check 2.1.6 in `cfg/1.6/node.yaml`.

Without passing in kubeconfig credentials:

```bash
$ docker run --pid=host -v /etc:/etc:ro -v /var:/var:ro -v $(which kubectl):/usr/bin/kubectl -t lizrice/kube-bench:5e6cdfdb master -v 1
I0628 16:52:06.591683    6099 util.go:367] Unable to get Kubernetes version from kubectl, using default version: 1.6
I0628 16:52:06.591822    6099 common.go:74] Using benchmark file: cfg/1.6/master.yaml
...
```
As updated in the README with this fix:

```bash
docker run --pid=host -v /etc:/etc:ro -v /var:/var:ro -v $(which kubectl):/usr/bin/kubectl -v ~/.kube:/.kube -e KUBECONFIG=/.kube/config -t lizrice/kube-bench:5e6cdfdb master -v 1

If kube-controller-manager is getting detected by older versions of
procps, it will only be detected if we're looking for kube-controller
(15 chars)

NOTE: "The command name is not the same as the command line. Previous versions of
       procps and the kernel truncated this command name to 15
       characters. This limitation is no longer present in both. If
       you depended on matching only 15 characters, you may no longer
       get a match."

* Remove binary that was accidentally added

https://github.com/aquasecurity/kube-bench/commit/911e9051dc2d53ecef957794df75325ca1f4bfa8
