Patch ICU to remove unwanted data.

We don't need all the ICU data and we need to reduce binaries' size
(Especially for android where we have a limit of 50Mo per APK).

By removing unwanted ICU data, we reduce a lot the data size and so
the final binaries' size.

There is also some "problems" to compile the `ja.txt` collfiles,
the "resource compiler" crashes.
As we don't need it, we also remove it.
