kubeadm: fix ImagePullCheck output

**What this PR does / why we need it**:

ImagePullCheck outputs "pulling <image>" line even if image
already exists and is not pulled.
    
Fixed the output to reflect the reality. ImagePullCheck now outputs
either "pulling <image>" or "image <image> exists".

**Release note**:
```release-note
NONE
```
