Dockerfile: fix golang-ci-lint installer

We were using "go get", whith would try to fetch some dependencies
that are not in the version we're installing,

    go get -d github.com/golangci/golangci-lint/cmd/golangci-lint

Causing the build to fail;

    package 4d63.com/gochecknoglobals/checknoglobals: unrecognized import path "4d63.com/gochecknoglobals/checknoglobals" (parse https://4d63.com/gochecknoglobals/checknoglobals?go-get=1: no go-import meta tags ())
