Fix windows UT for proxy mode

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

/kind bug

Fix windows UT for proxy mode.

Run UTs for `kubeproxyconfig/validation` in windows,

```
=== RUN   TestValidateKubeProxyConfiguration
--- FAIL: TestValidateKubeProxyConfiguration (0.00s)
        validation_test.go:83: expected success: [KubeProxyConfiguration.Mode.ProxyMode: Invalid value: "ipvs": must be kernelspace,userspace or blank (blank means the most-available proxy [currently userspace])]
```

That's because proxy mode "IPVS" is not valid in windows.
