OpenCV CUDA variables update

[HoneyPatouceul]

Running L4T R32.6.1 on AGX Xavier.
Seems recent opencv versions don't show "Use Cuda" in getBuildInformation() used by opencv_version --verbose.
Sorry I'm unable to make a PR, but it may be possible to get opencv CUDA availabilty with:

opencv_version --verbose | grep  "CUDA" | cut -f2 -d ':' | tr -s ' ' | cut -d' ' -f2

and opencv CUDA supported version with :

opencv_version --verbose | grep  "CUDA" | cut -f2 -d ':' | tr -s ' ' | cut -d' ' -f4 | cut -d',' -f1

Hi @HoneyPatouceul

if I well understand I fixed using your hints:

and

https://github.com/rbonghi/jetson_stats/blob/develop/jtop/jetson_libraries#L49

Let me know if make sense for you as well

@rbonghi yes, that's the suggested change. Not tested, though. Feel free to close the issue when verified.
