hack/tools: use same golangci-lint as Kubernetes

Depending on the more recent golangci-lint 1.43.0 also pulls in a newer mock
package, which caused problems when trying to use the logcheck plugin in
Kubernetes because there were problems with generated mock files when using the
newer mock.

By sticking with the same golangci-lint as Kubernetes such problems get avoided
and the tools can be updated independently in Kubernetes.
