Fix spec/ruby/command_line/rubylib_spec.rb for use with make test-spec

* Current code clears ENV['RUBYLIB'], but on Windows it's needed when
  running from build 'src' (or running make test-spec).
* Patch by MSP-Greg, from https://github.com/ruby/spec/pull/607.
* Imported manually to fix CI on Windows, without needing a full sync.
