Kir Kolyshkin f0cab0e285 TestImportExtremelyLargeImageWorks: optimize DevZero
According to https://github.com/golang/go/issues/5373, go recognizes
(and optimizes for) the following syntax:

```go
for i := range b {
	b[i] = 0
}
```

so let's use it. Limited testing shows ~7.5x speed increase,
compared to the previously used syntax.
