[autotest-client-tests][PATCH 1/1] UBUNTU: SAUCE: ubuntu_nvidia_server_driver: increase curl resilience

[Taihsiang Ho (tai271828)]

The nvidia-fs testing job sometimes fails for fetching gpgkey from
nvidia's docker github repository:

    + curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey
    + sudo apt-key add -
    gpg: no valid OpenPGP data found.

We can improve the corresponding curl resilience and dump more error
logs for post-moderm with this commit.
