Fix test for chunk-writing case

A few runs that resulted in bad timings for chunk-sized writes led Jan
Kara and Mike Galbraith to discuss why it might be so and Mike spotted
the error in the code -- we allocated a buffer of the size of the file
instead of the size of the chunk -- in my case, 4G instead of 4K.

Thanks Mike.
