provision_llama_cuda: put Linux dirs first in PATH (WSL interop hygiene)

Browse source 
When the installer is launched from a Windows shell, WSL interop leaks the Windows
PATH (/mnt/c/... entries, with spaces) into the build environment, which can make
cmake/gcc/git resolve to Windows tools or otherwise confuse the CUDA build. Prepend
the CUDA toolkit + standard Linux dirs so the Linux toolchain always wins; keep the
original PATH after so nvidia-smi etc. still resolve.
