devel/icu: Revert hostile 34b444edf6319efbf1ee2c8b75e3e4db1f72378c

It is already part of my patch (attachment 256309 of PR 278420 [1]) which is set maintainer-approval+ [2].

However, it was intentionally ignored when diizzy@ committed 2dd24161c13d36a514a19fe5fea94260400b44de [3].

Comparing to his own patch [4], [1] also fixes PORTREVISION which is committed but missing in his commit log.

Instead, he declared my patch [1] as "mainly style changes".
