In LLVM unified builds `%swift_obj_root` points to `<LLVM build dir>/tools/swift`, and folders like `bin`, `lib` and `share` are not under `swift_obj_root`, which makes some tests fail. For the cases in which `%swift_obj_root/lib` was used, replace it by using `%swift-lib-dir` instead. Replicate `%swift-lib-dir` to create `%swift-bin-dir` and `%swift-share-dir`, and use those instead of `%swift_obj_root/bin` and `%swift_obj_root/share`. This alternates work both in Swift build-script builds and also in LLVM unified builds.
