RubyGems installed the following executables:
	/home/deivid/.rbenv/versions/2.7.1/bin/gem
	/home/deivid/.rbenv/versions/2.7.1/bin/bundle

```

This is because the `$LOAD_PATH` entry added by `setup.rb` is relatively
and when the offending require happens, we're installing `bundler` and
have switched folders to `bundler/`. So the require fallsback to the
system rubygems.

To avoid that, add an absolute path to the `$LOAD_PATH`.

On jruby, somehow the $LOAD_PATH is manipulated so that we end up
requiring stuff inside the built package even if we have specified the
`-I` flag, so we get redefinition warnings anyways.

I'm not sure about the root cause, but relative requiring fixes it, and
it's faster anyways.

Merge master branch from rubygems/rubygems upstream.
