update list of generic cni binaries

New version of hyperkube image is missing cnitool and noop cni binary so
we should remove them.

```
cluster docker run --rm -ti  gcr.io/google_containers/hyperkube-amd64:v1.9.1 ls /opt/cni/bin/ | sort
bridge	flannel     ipvlan    macvlan  ptp     tuning
dhcp	host-local  loopback  portmap  sample  vlan
cluster docker run --rm -ti  gcr.io/google_containers/hyperkube-amd64:v1.8.4 ls /opt/cni/bin/ | sort
bridge	 dhcp	  host-local  loopback	noop  tuning
cnitool  flannel  ipvlan      macvlan	ptp
```
