Fancontrol: add test etc from #70933 (#72065)

* lm_sensors: add fancontrol module + nixos test

fancontrol is a small script that checks temperature sensors and adapts
fan speeds accordingly. It reads a text config file that can be
auto-generated by running the pwmconfig wizard on the live system.
