llvmPackages_13.libcxxabi: Align with 11 libcxxabi

Browse Source 
LLVM 11 libcxxabi has some flags to support usage in the Darwin stdenv,
in particular, `standalone` and `withLibunwind`.

Darwin stdenv needs the `standalone` flag because its `hostPlatform` set
doesn't have `useLLVM` set to true. And it needs `withLibunwind` to
explicitly disable including `libunwind` as a build input.

We also prefix `install_name_tool` in case we're cross-compiling.
