Update go version to 1.14.4 (elastic#19753)

## What does this PR do?

This PR adds support for Golang 1.14.4 in Beats. The dependency `golang.org/x/tools` is pinned to `release-branch.go1.14`.

The generated Beats no longer contain a vendor folder.

## Why is it important?

Go 1.14 has been out for quite some time. It is high time we update.

## Related issues

Closes elastic#18829
Closes elastic#16566
