Fix driver tests when `LLVM_ENABLE_PER_TARGET_RUNTIME_DIR` is `ON`

[broadwaylamb]

Summary

Some Driver tests relied on the default resource direcory having per-os per-arch subdirectory layout, and when clang is built with -DLLVM_ENABLE_PER_TARGET_RUNTIME_DIR=ON, those test fail, because clang by default assumes per-target subdirectories.

Explicitly set -resource-dir flag to point to a tree with per-os per-arch layout.
