[text-decorations] Use range in fuzzy for `text-decoration-subelements-002.html`

After the fix crrev.com/c/3748547, the test in the wpt[1]
fails in Firefox too. Re-reading the spec[2], "max" means the
maximum value in the pixels of a PNG, not the maximum value
it can take. When it may vary, the values must be in the range
syntax.

This patch allows 0 for both `maxDifference` and `totalPixels`
so that exact match is also allowed.
