kubemark: static binary, replace deprecated --log-file parameter

The --log-file parameter will be deprecated as of Kubernetes 1.23 and should be
avoided. The replacement for distroless images is the image with go-runner, a
tool that handles output redirection.

For kubemark to run in that image it must be built as static binary.
