`rake install` command is failed (#1170)

* `rake install` command is failed

\### Problems

Several file paths were changed by following PR.

- https://github.com/ruby/rdoc/commit/4211292ffe80dd4737db2450d72df404a9d55051
- https://github.com/ruby/rdoc/commit/d7bca12c13b8b3f1632d698d497e67d4ea8a88bc

Because rdoc.gemspec doesn't take in this changes,
the `rake install` command is permanently failed.
