python3Packages.pythran: unvendor the xsimd dependency

https://hydra.nixos.org/build/229711355/nixlog/150/tail
https://github.com/NixOS/nixpkgs/pull/246200#issuecomment-1658719714

pythran doesn't seem to support building with external xsimd,
but this source-symlink seems to work fine and it's header-only
C++ library anyway.
