hwmon-temp-sensor: Support sensor with missing labels
Currently the hwmon temp sensors forces all sensor labels to be
required even when we don't want to expose all of them.
For example,
```
{
"Address": "0x4e",
"Bus": "$bus",
"Name": "test0",
"Name1": "test1",
"Name2": "test2",
"Name3": "test3",
"Labels": ["temp4"],
"Type": "MAX31730"
},
```
It will have
```
$ /tmp/hwmontempsensor &
error getting SpecialMode status No route to host
malloc(): unsorted double linked list corrupted
-sh: line 438: 20466 Aborted (core dumped)
/tmp/hwmontempsensor
```
It needs the `Labels` to be `["temp1, "temp2", "temp3", "temp4"]` to
work properly.
With the fix to the daemon it doesn't need it anymore and we can expose
only the sensor that we want.
Tested:
Working and didn't crash

dbus-sensors is a collection of sensor applications that provide the xyz.openbmc_project.Sensor collection of interfaces. They read sensor values from hwmon, d-bus, or direct driver access to provide readings. Some advance non-sensor features such as fan presence, pwm control, and automatic cpu detection (x86) are also supported.
runtime re-configurable from d-bus (entity-manager or the like)
isolated: each sensor type is isolated into its own daemon, so a bug in one sensor is unlikely to affect another, and single sensor modifications are possible
async single-threaded: uses sdbusplus/asio bindings
multiple data inputs: hwmon, d-bus, direct driver access
