Traceback when trying to install drivers as normal user

[Jeff Lane ]

Forgot to use sudo and discovered an ugly traceback.

ubuntu@doubletusk:~$ ubuntu-drivers --gpgpu install
This is gpgpu mode

This is because I forgot to use sudo to do the install

ubuntu-drivers can do somethings as a non-privileged driver but other things (install) requires root escalation.

ubuntu-drivers should either always require root via sudo, or "ubuntu-drivers install" should do a user check and exit with a simple helpful message like "You must use sudo when installing drivers".
