Subject: [PATCH] Fix build with poppler-26.04+

Upstream Poppler changed Gfx8BitFont::getEncoding() to return
'const std::array<const char*, 256>&' instead of 'char**'. Adapt
the two call sites in poppler-cairo-font-engine.cpp accordingly.

The cast is safe because both call sites only read enc[i].

Bentoo overlay patch — not yet submitted upstream.
