[clang] [LinkerWrapper] Fix 'save-temps' when targeting SPIR-V (PR #144605)

[Joseph Huber via cfe-commits]

https://github.com/jhuber6 created https://github.com/llvm/llvm-project/pull/144605

Summary:
The logic here is flawed, it was only intended to apply to the CPU case
where we use the linker passed in on the command line. This was falsely
applying to SPIR-V which caused issues.
