All 6 case-sensitivity shim headers in tools/linux/overlay/include/ now use #include_next instead of #include to forward to the real MinGW system header, avoiding infinite preprocessor recursion on Linux (Debian/WSL) where overlay/include is first in the search path. Fixes build failures on Debian WSL (GCC 12) for all configurations. Also update nsis7z.dll binaries built with the fixed overlay.
