[OpenBSD] Add support for sensors_temperatures

[TheQue42]

Summary

• OS: OpenBSD
• Type new-api

Description

Currently, in psutil 5.8 on openbsd 6.8, the sensors_temperatures returns:

AttributeError: module 'psutil' has no attribute 'sensors_temperatures'

The values are available (providing the system runs the sensorsd) at:

#> sysctl hw.sensors
hw.sensors.cpu0.temp0=43.00 degC
hw.sensors.acpitz0.temp0=27.80 degC (zone temperature)
hw.sensors.acpitz1.temp0=29.80 degC (zone temperature)
hw.sensors.pchtemp0.temp0=39.00 degC

It would be really good if this api call could be supported on openbsd.

Probably because I'm running a virtualized OpenBSD via Vagrant, I only have access to these:

openbsd64$ sysctl hw.sensors
hw.sensors.acpibat0.volt0=10.00 VDC (voltage)
hw.sensors.acpibat0.volt1=10.00 VDC (current voltage)
hw.sensors.acpibat0.power0=0.00 W (rate)
hw.sensors.acpibat0.watthour0=50.00 Wh (last full capacity)
hw.sensors.acpibat0.watthour1=0.10 Wh (warning capacity)
hw.sensors.acpibat0.watthour2=0.05 Wh (low capacity)
hw.sensors.acpibat0.watthour3=49.50 Wh (remaining capacity), OK
hw.sensors.acpibat0.watthour4=50.00 Wh (design capacity)
hw.sensors.acpibat0.raw0=0 (battery idle), OK
hw.sensors.acpiac0.indicator0=On (power supply)

If you know how to do it feel free to make a PR though.
