logging: replace direct journal calls with lg2

Tested:

Created a bogus journal message equivalent to the one in
TachSensor.hpp as the first line of 'main' in FanMain.cpp:

```
    auto device = "FooBar";
    auto msg = "OpenBMC.0.1.FanInserted";
    lg2::error("Fan Inserted", "REDFISH_MESSAGE_ID", msg,
               "REDFISH_MESSAGE_ARGS", device);
```

Observed the following in the journal:
```
