Entropy warning thresholds need to be revisited

As per the following, newer kernels (5.15+) have recalibrated the entropy levels from 0-4096 to 0-256. Hence, everything is throwing a warning:

Warning: Available entropy is low. As a result, use of the UUIDField, SSL, or any other features that require
RNG might not work properly. To check for the amount of available entropy, use 'cat /proc/sys/kernel/random/entropy_avail'.

Here's where I found out about this change:

We might need to intelligently report the low entropy (based on kernel version).
