libcxx: Link libc++.dylib to matching libc++abi.dylib

Same adjustment as made for libc++abi in #185766, for the same reason:
the unamended dylib links to the libc++abi in the build stdenv, which
is the wrong version.

Tested on Darwin with LLVM 14 stdenv, but the phase is added to all
versions, including 11 - so this will cause a mass rebuild.

See: https://github.com/NixOS/nixpkgs/pull/185766
