Fix cpu temperature reporting for Armbian on Odroid (#48903)

Browse Source 
Some systems expose cpu temperatures differently in
psutil. Specifically, running armbian on the Odroid xu4 sbc gives the
following temerature output:

>>> pp.pprint(psutil.sensors_temperatures())
{   'cpu0-thermal':
    [   shwtemp(label='', current=54.0, high=115.0, critical=115.0)],
    'cpu1-thermal':
    [   shwtemp(label='', current=56.0, high=115.0, critical=115.0)],
    'cpu2-thermal':
    [   shwtemp(label='', current=58.0, high=115.0, critical=115.0)],
    'cpu3-thermal':
    [   shwtemp(label='', current=56.0, high=115.0, critical=115.0)],
}

Since the cpu number is embedded inside the name, the current code
can't find it.

To fix this, check both the name and the constructed label for matches
against CPU_SENSOR_PREFIXES, and add the appropriate label
cpu0-thermal in the prefix list.

While this is slightly less efficient that just generating the label
and checking it, it results in easier to understand code.
