Linux/LibSensors: adjust data for k10temp

[cgzones]

Adjust the temperature data gathered from the k10temp driver. Only a control value, an optional die value, and one value per CCD are provided.

See https://www.kernel.org/doc/html/latest/hwmon/k10temp.html for details.

Re the double->float patch: While we are not showing anything more than 1 fractional digit, the data acquisition is done using doubles, thus sticking to keeping the native type here is IMO preferable (avoids rounding errors due to type conversion).

Might get superseded by #1352.
