Provide a way to select which sensor to use for CPU temperature

[hrw]

At the moment htop has hardcoded list of x86-64 cpu sensors. So it does not read them on my computers ;(

[hrw@jagular htop]$ sensors
acpitz-acpi-0
Adapter: ACPI interface
temp1:        +61.0°C  (crit = +95.0°C)
temp2:        +60.0°C  (crit = +95.0°C)
temp3:        +61.0°C  (crit = +95.0°C)
temp4:        +60.0°C  (crit = +95.0°C)
temp5:        +60.0°C  (crit = +95.0°C)
temp6:        +60.0°C  (crit = +95.0°C)
temp7:        +60.0°C  (crit = +95.0°C)
temp8:        +59.0°C  (crit = +95.0°C)
temp9:        +60.0°C  (crit = +95.0°C)

For now I added 'acpitz' to hardcoded list but that's not a good solution.

Just FTR acpitz = ACPI Thermal Zone

Why is it closed?

It is not possible to choose lm_sensors value.

I need to choose motherboard sensor, because only that one is accurate.
