Currently a lot of the .po locale files are generated using iconv to different encodings. This is only necessary if the version of Vim does not have iconv and cannot dynamically convert encoding, which isn't the case for MacVim. Furthermore, MacVim should only work in UTF-8 anyway, so it's not useful to have all the other non-UTF-8 locales (e.g. zh_CN.cp936.po) being built and bundled together, as they make the build process more complicated and bulk up the binary size of the app bundle.
Simply modify the Makefile to not install / build any of the duplicate locale files. For locales like ko/zh_CN/zh_TW, where the "base" version ko.po is in a non-UTF-8 locale and converted from a ko.UTF-8.po, we keep only the ko.UTF-8.po version, but during install we install the folder as "ko" instead of "ko.UTF-8". This way, if someone somehow set LANG=ko_KR, it will still work instead of having to set LANG=ko_KR.UTF-8.
Currently, pl.po is an odd one out because pl.UTF-8.po is actually generated from pl.po, instead of the other way round. We just use pl.po since that's the source version, instead of using the generated UTF-8 one for simplicity (MacVim can handle it fine).
Also, revert the MacVim-local translations made to these non-UTF8 locales like zh_CN.cp936.po, since we don't use them anymore in MacVim builds.
Saved ~2 MB in the app bundle, and ~1MB in the generated dmg.
