Always re-measure non-embedded ArialNarrow fonts (bug 1671312, PR 12725 follow-up)

Browse source 
While PR 12725 fixed bug 1671312 as reported, i.e. the "In the upper right corner "Purposes' has bad kerning."-part, it however broke other parts of the text rendering.
Note in particular the tables, e.g. on page 2 and beyond, where the glyphs are now rendered too close together. The reason for this is that the fonts in question are non-embedded ArialNarrow, which we just replace with Helvetica which obviously is not narrow. Given that the font replacement isn't a perfect fit for non-embedded ArialNarrow, we still need to re-measure the glyph widths in this case.
