chromium: temporarily work around stdenv/patchShebangs.sh bug

      # We need the fix for https://bugs.chromium.org/p/chromium/issues/detail?id=1254408:

      base64 --decode ${clangFormatPython3} > buildtools/linux64/clang-format

      # Add final newlines to scripts that do not end with one.

      # This is a temporary workaround until https://github.com/NixOS/nixpkgs/pull/255463 (or similar) has been merged,

      # as patchShebangs hard-crashes when it encounters files that contain only a shebang and do not end with a final

      # newline.

      find . -type f -perm -0100 -exec sed -i -e '$a\' {} +

      patchShebangs .

      # Link to our own Node.js and Java (required during the build):

      mkdir -p third_party/node/linux/node-linux-x64/bin
