checks: Update outdated nvidia drivers detection

[Penwy]

Description

This updates the nvidia drivers check to include the new log message for it in v31.

I also took the opportunity to remove unnecessary len() calls in that file (python lists have always positive length and a list with a length of 0 has a bool value of False).

Motivation and Context

The new nvidia implementation in v31 has different behaviour with outdated drivers and wasn't getting detected.

How Has This Been Tested?

Ran analyzer on a log with outdated drivers, verified message appeared.
