Subject: [PATCH] llvmPackages.lldb: combine `out` and `lib` outputs on Darwin

LLDB expects to find the location of `bin` relative to `lib`. Patching
it to know the location would cause a cycle between the `out` output and
the `lib` output, so combine the two on Darwin.

Fixes https://github.com/NixOS/nixpkgs/issues/252838.
