Update kazel to include openapi tag detection fix

**What this PR does / why we need it**: includes the fix from https://github.com/kubernetes/repo-infra/issues/67 for https://github.com/kubernetes/repo-infra/issues/66, which was discovered in @thockin's PR https://github.com/kubernetes/kubernetes/pull/57600/files#r178665554.

**Special notes for your reviewer**: I'm not sure what's up with the large list of comment diffs in `Godeps.json`; it looks like the `git describe` strings were (unintentionally?) truncated in @brendanburns's PR https://github.com/kubernetes/kubernetes/pull/61955.

**Release note**:

```release-note
NONE
```
