Sometimes the driver will hang and since this is used inside of `clang` to 
support `--offload-arch=native` I've had cases where the compiler hangs 
forever, so I added a timeout to keep it from doing that. This removes that 
possibility. It's faster and since this will be installed on every single LLVM 
build, not everyone has ROCm so it would be nice for this to work.
