lib: remove `env: node` in eslint config for lib files

This patch removes the redundant `require-globals` custom
eslint rule by removing `env: node` in the eslint config
and whitelist the globals that can be accessed in native
modules instead of black listing them. This makes sense
for our `lib/` files because here we are creating the
Node.js environment instead of running in a normal user
land Node.js environment.
