Subject: [ruby/irb] Improve debug command tests
 (https://github.com/ruby/irb/pull/594)

* Use require_relative for envutil.rb

Requiring test helper files with `require_relative` allows running the tests
with `ruby -Itest test/irb/test_debug_cmd.rb` without having to set up
the load path.

* Replace reline hack with TERM=dumb
