Analyzing the docker layers of node:latest, node:slim and node:alpine images using dive

I found that the Yarn installation adds a /tmp/v8-compile-cache-0 with a size 2.2MiB in all these images and this is not needed for the users of theses images.

node:alpine

node:slim

node:latest

Also, the /var/cache and /var/log folders sounds useless.

Let me know if I can help submitting a PR with

rm -rf /tmp/*
