[#47] [Pipeline] Fix YDBGo pipeline failure in lint_code job due to G…

…O111MODULE=off

**Problem**

After bump YDBGo wrapper version to odd development version v1.2.5 in YDBGo!185, Daily pipeline failed with this error.
```shell
$ go get -u golang.org/x/lint/golint
345# golang.org/x/tools/go/types/objectpath
346/go/src/golang.org/x/tools/go/types/objectpath/objectpath.go:397:10: meth.Origin undefined (type *types.Func has no field or method Origin)
```

**Cause**

The cause of this problem likely to be `GO111MODULE=off` (Reference : dominikh/go-tools#653, #47).
From the reference GO111MODULE=off might have some problem with linter.

**Solution**

Change `GO111MODULE=off` to `GO111MODULE=on` but in only lint_code section to reduce impact to the whole pipeline.
But after `GO111MODULE=on` some change need to be apply here because we're using Go module.

After some research, `go get -u golang.org/x/lint/golint` need to change to `go install golang.org/x/lint/golint@latest`.

`go get` when `GO111MODULE=off` will download source package and compiled it to a binary but `GO111MODULE=on`, it won't.
So, `go install` would be a solution because it will download source code and compile it to binary as we want.
