refactor: drop golang.org/x/lint (elastic#5130)

the dependency was used to install the golint tool. The golint tool is frozen
and deprecated according to the upstream repository: https://github.com/golang/lint

CI and automation are using golangci-lint and enable staticcheck which is mentioned
as a valid replacement.
