Subject: [PATCH] Do not upload log artifact when no log is present

- This fixes #207, older CUDA versions don't have an installer log at
  the hardcoded location of /var/log/cuda-installer.log so the
  artifact uploader would fail.
- To fix this let's not upload any artifacts in the first place if there
  is no log file to upload.
