Changes in this update:
- Enable the Jieba segmentation plugin via a new JIEBA option (default on).
- OpenCC now requires C++17: USES compiler:c++11-lib -> c++17-lang.
- Regenerate files/patch-CMakeLists.txt for the reorganized upstream tree.
- Add files/patch-cmake_GitVersion.cmake so the release tarball (which
ships without Git metadata) reports 1.4.1 instead of 1.4.0.
Obtained from upstream commit c23e743702f4.
