Re-integrate with linux-on-mac/mbpfan fork

[gaul]

I don't understand the history of this fork but it would be good to get any relevant patches into linux-on-mac/mbpfan so the distribution package can include all the functionality. Please let me know how I can help.

This fork's only change is to add a script to find the proper fan device path on T2 machines.

IIRC someone claimed to have found a universal path that wouldn't have to be determined at build time, but I don't have a large enough sample size to hardcode that path (which would be easily upstreamable).

My involvement in the t2linux project has also lowered quite a bit, it's probably best to talk to active contributors on the discord server linked on https://t2linux.org
