Include more up to date it87 module

Problem/Justification
I would like for TrueNAS scale to include newer version of it87 module in their builds. This module includes support for reading/controlling some useful sensors. There is already some version of this module present, but it sadly does not support the sensors I need.

Newer version is available on github:
“frankcrawford/it87”

Impact
This will help people that use newer gigabyte motherboards and want to control their fan speeds. Generally, it should help anyone that wants to access the newly supported sensors.

User Story
I am trying to control system fan speed based on the temperatures of my disks, because I have a serious overheating issue. I was trying to use hddfancontrol to control the system fans. When I tried to run sensors command, my fans were not visible at all. After some searching on the internet I have found out that I need an updated version of the it87 module.

The newer version has support for the controller on my motherboard (IT8689E).
