Title: Use DejaVu Sans Book as a fallback for bold/italics

DejaVu Sans Book has 5942 glyphs while bold and italic have 5868 and 5155 glyphs.

They may not quite match, but unifont doesn't have bold or italic glyphs at all so it's still closer.

Glyph counts
```
5085 /usr/share/fonts/truetype/ttf-dejavu/DejaVuSans-BoldOblique.ttf
5155 /usr/share/fonts/truetype/ttf-dejavu/DejaVuSans-Oblique.ttf
5868 /usr/share/fonts/truetype/ttf-dejavu/DejaVuSans-Bold.ttf
5942 /usr/share/fonts/truetype/ttf-dejavu/DejaVuSans.ttf
63449 /usr/share/fonts/truetype/unifont/unifont.ttf
```

This is the small improvement mentioned in #294
