Daniel Rodríguez Troitiño 8f0382c109 [test] Replace swift_obj_root for alternates that work in LLVM unified builds (#66167)
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.
