If the following conditions are met:
* You have a default version of fileutils and a higher version of
fileutils installed as a regular gem. This case is common on ruby 2.6.
* You use a bundler generated binstub on a gem setup with a `Gemfile`
using the `gemspec` DSL.
Then `fileutils` redefinition warnings happen because of the following:
The gist of a bundler generated binstub is:
```ruby
require "bundler/setup"
load Gem.bin_path("rake", "rake")
```
First configure bundler, then load the requested gem.
When `require "bundler/setup"` is called under the previously mentioned
setup, `ext_conf_builder.rb` ends up being required because of the new
validation that gemspecs with rake extensions depend on `rake`. And that
loads the latest version of `fileutils` because of using "rubygems
monkeypatched require" that auto-chooses the latest version of default
gems.
After that, when `Gem.bin_path` gets called, `ext_conf_builder.rb` gets
required again, but this time already using "bundler's unmonkeypatched
require" which means the default version is chosen and thus the
redefinition warning happens.
The solution as usual is to lazily load `fileutils`.
