[en] Only use a kludge for Chinese when lang_code == zh

CURRENTLY FAILS NEW TEST, I DON'T KNOW WHY

Fixes #1520

A kludge for Chinese etymology and pronunciation sections
and subsequent changes to them in PR #1303 breaks the
data-stuffing of etymology sections with level-4 prons that
are preceded by similar sections. Prons from the previous
etymology are put into the following one, twice (before
and after).
