gnu: ruby-yard: Refactor package and some dependencies.

Replace ruby-yard and ruby-yard-with-tests with ruby-yard and
ruby-yard/minimal.  This introduced some cycles, so add some additional
minimal variants to avoid this.

* gnu/packages/ruby.scm (ruby-asciidoctor/minimal, ruby-test-unit/minimal,
ruby-yard/minimal): New variables.
(ruby-rubygems-tasks)[native-inputs]: Remove unnecessary ruby-spec and
ruby-yard.
(ruby-locale, ruby-gettext, ruby-tdiff, ruby-nokogiri-diff,
ruby-public-suffix, ruby-addressable)[native-inputs]:
Switch to ruby-yard/minimal.
(ruby-metaclass)[native-inputs]: Switch to ruby-test-unit/minimal.
(ruby-yard): Update to 0.9.34.
[arguments]: Update style, don't disable tests, specify #:test-target, and
patch spec/cli/diff_spec.rb.
[native-inputs]: Add from ruby-yard-with-tests.
(ruby-yard-with-tests): Remove variable.
