unittests: Fixes server journal unit test on Windows

[claudiubelu]

What type of PR is this?

/kind failing-test
/sig windows
/sig testing

/priority important-soon

What this PR does / why we need it:

The Boot option for the node log query is not supported on Windows and an error is returned if the option is set. Because of this, one of the unit tests which sets the option fails, as it does not expect any errror.

Sample error: https://prow.k8s.io/view/gs/kubernetes-jenkins/logs/ci-kubernetes-unit-windows-master/1643774435150270464

{Failed  === RUN   Test_nodeLogQuery_validate/boot
    kubelet_server_journal_test.go:206: nodeLogQuery.validate() error = [boot: Invalid value: -1: boot is not supported on Windows], wantErr false
--- FAIL: Test_nodeLogQuery_validate/boot (0.00s)
}
