[llvm] Bypass sandbox in `sys::fs::createTemporaryFile()` (#174491)

Based on the name of the function, I think it's safe to assume
`sys::fs::createTemporaryFile()` is not to be used for formal compiler
outputs and should only be used for compiler-internal outputs (caches,
debugging output, etc.). Thus, it should be fine to disable the IO
sandbox and allow bypassing `vfs::OutputBackend` here.
