Revert "Add browserify/babelify info to package.json"

The intent of that commit was to show the original source files when
debugging. However, having babelify as a dependency (instead of just
babel as a devDependency) is annoying, so we're going to simply publish
./lib/index.js.map (containing sourcesContent) alongside ./lib/index.js

This reverts commit 40502217a793bbf84f9fe1533c8f1eb48a248bbe.
