fix: skip global.js transform

[underfin]

Description

Here is code of global ployfill, the code has global key words, it will transformed and add import '\0polyfill-node:global.js'. But it is a self import, so we need skip it.

export default (typeof global !== "undefined" ? global :
  typeof self !== "undefined" ? self :
  typeof window !== "undefined" ? window : {});

Indeed, using it results in the following -

(!) Circular dependencies
polyfill-node:global.js -> polyfill-node:global.js

A look/merge at this proposed solution would be appreciated.
