Subject: lib/webrick.rb: use require_relative for webrick/utils.rb

`require "webrick/utils.rb"` should load `lib/webrick/utils.rb`, but on
some CI machines, it wrongly loads `test/webrick/utils.rb`, which caused
circular require warning:

https://rubyci.org/logs/rubyci.s3.amazonaws.com/ubuntu/ruby-master/log/20190825T093007Z.log.html.gz
```
