sensor_service: add DARWIN48V platform support (#261)

Summary:
# Description

Adds initial `sensor_service` support for `DARWIN48V` platform. Note that this depends on the changes in #257. Monitored sensors are the same as `DARWIN` platform with the exception of PSU replacing PEM.

Pull Request resolved: #261

Test Plan:
FBOSS OSS build passes with CentOS 9 and Linux kernel 6.4.

Validated on DARWIN48V hardware.

The `sensor_service` loads correctly:
```
# systemctl status sensor_service
● sensor_service.service - Start sensor_service
     Loaded: loaded (/etc/systemd/system/sensor_service.service; enabled; preset: disabled)
     Active: active (running) since Tue 2024-10-08 00:39:22 UTC; 1h 49min ago
   Main PID: 4894 (run_sensor_serv)
