Merge pull request #26399 from ixdy/jenkins-unittest-build

Automatic merge from submit-queue

Avoid duplicate building in Jenkins unit/integration job

Partially adopts #26392: don't run `hack/build-go.sh` in the unit/integration job, since we do that already for e2e.

We do need to still build kubectl, however, so do that in `hack/test-cmd.sh`.
