fix: keep CRLF when patching CPython on Windows

Browse Source 
git apply inherits the caller's configuration, so under core.autocrlf=input it
rewrites the patched PCbuild/find_python.bat to LF. cmd.exe cannot resolve goto
labels in an LF batch file, so CPython's build fails with "The system cannot
find the batch label specified - begin_search" and then "Cannot locate
python.exe on PATH or as PYTHON variable".

git init already runs in the extracted source, so setting core.autocrlf on the
repository it creates is enough, without touching the shared PATCH_CMD.
