Adjust test expectations for infinite-size images.

The test for infinite-size images is expecting the width to be equal to
the maximum possible value of a blink layout value. However, with
use-zoom-for-dsf on and device scale factor !=1 all image widths are
adjusted by the scale factor. So the test's expectation needs to be
changed because the effective maximum value is now different.
