[text-box-trim] Fix text-box-trim-initial-letter-start-001-ref

This patch fixes the test to be interoperable.

It turned out that the font size of raised initial letters is
undefined[1], and implementations have different issues
especially when using Ahem as a web font.

To make this test focus on if the text-box-trim property
trims the raised part, this patch fixes the ref file to
compute the position dynamically.

Locally tested on Blink and WebKit TP with -webkit- prefix
added to the initial-letter property.
