fix: CPU temperature on AMD machines

[pschmitt]

Noticed that the CPU temps on my Lenovo X13 Gen1 were not reported correctly (state: unknown).

Here's the output of sensors on that machine:

amdgpu-pci-0600
Adapter: PCI adapter
vddgfx:      812.00 mV
vddnb:       612.00 mV
edge:         +44.0°C
PPT:           5.00 W

thinkpad-isa-0000
Adapter: ISA adapter
fan1:           0 RPM
fan2:           0 RPM
CPU:          +44.0°C
GPU:           +0.0°C
temp3:         +0.0°C
temp4:         +0.0°C
temp5:         +0.0°C
temp6:         +0.0°C
temp7:         +0.0°C
temp8:            N/A

nvme-pci-0100
Adapter: PCI adapter
Composite:    +32.9°C  (low  = -273.1°C, high = +83.8°C)
                       (crit = +84.8°C)
Sensor 1:     +32.9°C  (low  = -273.1°C, high = +65261.8°C)
Sensor 2:     +29.9°C  (low  = -273.1°C, high = +65261.8°C)

iwlwifi_1-virtual-0
Adapter: Virtual device
temp1:        +37.0°C

k10temp-pci-00c3
Adapter: PCI adapter
Tctl:         +44.4°C

BAT0-acpi-0
Adapter: ACPI interface
in0:          11.53 V

Notice that there's no Package id line, but a CPU one.
