Fix the Ahem assumption test

8624366d45 tried to change the test in line with the modern requirement that Ahem is not a system font.

However, in actuality it just ended up testing that:

<span style="font: 15px/1 Ahem">X</span>

!=

<span style="font-size: 15px; line-height: 1;">X</span>

This test fails in Safari, because unsurprisingly 15px / 15px serif is the same as 15px / 15px Ahem when Ahem is not installed. It seems like it is actually testing that Ahem is installed, or at least is not a no-op.

Instead, simply test that Ahem's X is the same as serif's X, as this should be true without the font installed.
