Subject: [PATCH] Use null subunit for non-ISO currencies without a subunit

XFU and GBX defined subunit as an empty string in currency_non_iso.yml,
while currencies without a subunit in currency_iso.yml (e.g. JPY) leave
subunit null. Align the non-ISO entries with that convention.

Fixes Shopify/money#353
