CI: supply a font, not just the library

Message

The first CI run failed with "No test font found — set SIGIL_TEST_FONT or install fontconfig". The suite falls back to fc-match when SIGIL_TEST_FONT is unset, and a CI worker has no font cache; my laptop does, which is why this only appeared once it ran somewhere else.

Adds font-dejavu to the guix shell and points SIGIL_TEST_FONT at a known path inside the profile. Deterministic, where relying on fc-match to find something is not.
