Small fixes for Dutch

[ltguillaume]

It seems that the (English) banner.js string used to have "in" at the end, but not anymore.

This commit should fix that for Dutch, but some other translations still have "in" (translated) at the end, causing the end results be something like "Android will become a locked-down platform in in 183d 7h 25m 54s".

Thanks! Hopefully others can help fix the double "in". I'm not sure why that was ever the case (the English version has always been "Android will become a locked-down platform" with a trailing "in").

We actually reconsidered this in #166 and put the "in" back at the end of the English at 2356a78, so we might want to revert this. If you have a chance to take a look at the current Dutch and confirm that it now looks odd again, let us know (or submit a new PR adding back the trailing "in"…)

I see.

• I'll do a new PR to fix it for Dutch ✓
• Other languages are now missing the (translated) "in", such as German, Spanish and French
