[clang] [Driver] Use empty multilib file in another test (PR #111352)

[Oliver Stannard via cfe-commits]

https://github.com/ostannard created https://github.com/llvm/llvm-project/pull/111352

This makes the test independent of the one provided by a toolchain clang is built into, which can cause the output of
-print-multi-flags-experimental to change.
