Subject: [PATCH] Prevent clash with system GDAL

On macOS, I have GDAL 3.13.0 from Homebrew and rasterio's setup.py was mistakenly
using it instead of using GDAL from vcpkg port. The problem is that GDAL vcpkg port
deletes gdal-config (for whatever reason) and so the gdal-config from PATH (Homebrew)
gets picked and rasterio uses headers/libs from here. Then, when loaded against
GDAL from vcpkg (3.12.x) I was getting a nasty ImportError due to ABI mismatch.

The fix makes sure that rasterio ignores gdal-config, because there is no such
executable from GDAL vcpkg port anyway.
