Fixes umd build for non-web targets

[rigor789]

Starting with axios@0.21.2 - it fails to run in a NativeScript app. We can work around the issue by aliasing/defining window, but perhaps this affects more projects than just NativeScript.

In #3401 webpack has been updated to 4.x, which slightly modified the axios/dist/axios umd build:

/* axios v0.21.1 | (c) 2020 by Matt Zabriskie */
(function webpackUniversalModuleDefinition(root, factory) {
	if(typeof exports === 'object' && typeof module === 'object')
		module.exports = factory();
	else if(typeof define === 'function' && define.amd)
		define([], factory);
	else if(typeof exports === 'object')
		exports["axios"] = factory();
	else
		root["axios"] = factory();
})(this, function() {
// ^^^^ - this has changed between 0.21.1 and 0.21.2

/* axios v0.21.2 | (c) 2021 by Matt Zabriskie */
(function webpackUniversalModuleDefinition(root, factory) {
	if(typeof exports === 'object' && typeof module === 'object')
		module.exports = factory();
	else if(typeof define === 'function' && define.amd)
		define([], factory);
	else if(typeof exports === 'object')
		exports["axios"] = factory();
	else
		root["axios"] = factory();
})(window, function() {
// ^^^^^^ - this has changed between 0.21.1 and 0.21.2

After some searching, I found this issue in the webpack repo: webpack/webpack#6522 that describes the same scenario, and the proposed solution is to add globalObject: 'this' to preserve the old behavior.

With this fix, running npm run build correctly uses this as it used to.

Hey @jasonsaayman, is there anything I can help with to get this fix merged/released? Thanks!
