[Driver] Improve error when a compiler-rt library is not found (#81037)

BSD, Linux, and z/OS enable `LLVM_ENABLE_PER_TARGET_RUNTIME_DIR` by default. When a compiler-rt library is not found, we currently report an incorrect filename `libclang_rt.XXX-$arch.a` ``` % /tmp/Debug/bin/clang++ a.cc -fsanitize=address -o a ld.lld: error: cannot open /tmp/Debug/lib/clang/19/lib/linux/libclang_rt.asan-x86_64.a: No such file or directory clang++: error: linker command failed with exit code 1 (use -v to see invocation) ``` With this change, we will correctly report: ``` % /tmp/Debug/bin/clang++ a.cc -fsanitize=address -o a ld.lld: error: cannot open /tmp/Debug/lib/clang/19/lib/x86_64-unknown-linux-gnu/libclang_rt.asan.a: No such file or directory clang++: error: linker command failed with exit code 1 (use -v to see invocation) ``` Link: https://discourse.llvm.org/t/runtime-directory-fallback/76860
