Fix ICU data file for Android

In some locales, currency data turns empty after currency list filtering
on Android. This leads v8's currency formatter to fall back to 3-letter
currency code instead of currency symbol (e.g. 'GBP' in en-GB).

Fix the ICU data trimming script to remove an empty Currency block after
filtering and rebuild ICU data files.
