Fix that I18nTest#test_custom_pluralization_rules randomly fails (#36396, #36461).

Patch by Yuichi HARADA.

It seems that pluralization rules(config/locales/*.rb) is also loaded when loading the locale files located in I18n.load_path(source:/trunk/config/application.rb#L42).

One can ship pluralizers (i.e. lambdas that implement locale specific pluralization algorithms) as part of any Ruby translation file anywhere in the I18n.load_path. The implementation expects to find them with the key :pluralize in a (newly invented) translation metadata namespace :i18n.

Therefore, it seems that you can't set pluralization rules in the middle like I18nTest#test_custom_pluralization_rules.
I have confirmed that the tests succeed with the following patch.
