gate_dc_vs_lookdev: read the BLOCK path from the map as well

It hardcoded diffusion_gully_30km.hblk while the map moved to the 122.88 km
block — the two halves would have compared different terrain and reported it as
an engine/lookdev disagreement. Exactly the failure this function was written to
fix, one field further along.
