[Android] Set correct ICU default local for renderer processes.
For Android renderer processes, base::i18n::SetICUDefaultLocale was not
called. So base::i18n::IsRTL() returned incorrect value which made
offline error html page's text direction incorrect. Therefore, call
base::i18n::SetICUDefaultLocale on renderer process initialization.
