entity-manager: debug logs for loadConfigurations

Enable these logs to keep track of json load and parsing delay.

Tested: on Tyan S8030:

simulate fw update or developer changes:
```
rm /var/configuration/system.json
systemctl restart xyz.openbmc_project.EntityManager
```

journal output for one EM start
```

Repeating the benchmark a few times:

7668ms
6533ms
6838ms

3581ms
3601ms
3443ms

3638ms
3343ms
3381ms

The debug log shows how long the json parsing takes and helps with
future optimizations.
