Install extra TeX fonts on one runner only

jkseppan · jkseppan · commit d5ab3b02bbaf · 2025-06-06T09:12:50.000+03:00
The DejaVu and Heuristica fonts are used by the type-1 font
subsetting tests.

Heuristica has a Cyrillic encoding and apparently cannot be
loaded without installing texlive-lang-cyrillic.
