circular reference cause `inherits()` became empty object

the line below refs to `inherits()` from `inherits` module, but `inherits` module reference back to `util` module by checking the implementation on `util` module first, causing the first `require('inherits')` to returns empty object (default exports is empty object), if then `util.inherits()` gets call immediately it will throw.

problematic line in question:
https://github.com/browserify/node-util/blame/ef984721db7150f651800e051de4314c9517d42c/util.js#L592

the line needs to be updated to `require('inherits/inherits_browser')`

从 issue 中链接的 util.js 第 592 行开始，检查涉及 inherits 和 util 的循环 require。按照指定内容更新所引用的模块路径，然后验证 require util 并调用 util.inherits 时，在初始化期间不再遇到空的导出。
