[armhf][Nokia-7215]High CPU caused by entropy.py (#13694)
Why I did it
High CPU utilization by entropy.py

How I did it
Remove entropy script as it does not work anymore and is no longer needed for bullseye(202205).
In Buster(202012) the max available poolsize (entropy_avail) for entropy is 4096 and our entropy.py script was based on this value. With the change in kernel to bullseye on 202205 this entropy poolsize was changed to 256 which also causes our script to fail.

This script was initially added to provide SW assistance to improve the system entropy value available early on in the Sonic boot sequence on buster.
On bullseye (Linux kernel 5.10) this is no longer needed as this feature has been improved.

How to verify it
run "top" command to check CPU usage.
