entity-manager: fix representation: arrays of bool

This quirk came up during [1] and was fixed in sdbusplus in [2].

Fix the EM code now to drop this quirk.

According to statements in [2] there 'should' not be any effects of the
change, at least in upstream code.

Tested: on Tyan S8030.

entity-manager starts normally

```
Apr 03 20:35:36 s8030 systemd[1]: Started Entity Manager.
Apr 03 20:36:03 s8030 entity-manager[272]: Clearing previous configuration
Apr 03 20:36:15 s8030 entity-manager[272]: Inventory Added: Supermicro PWS 920P SQ 0
Apr 03 20:36:15 s8030 entity-manager[272]: Inventory Added: Supermicro PWS 920P SQ 1
Apr 03 20:36:15 s8030 entity-manager[272]: Inventory Added: Tyan S8030 Baseboard
Apr 03 20:36:15 s8030 entity-manager[272]: Inventory Added: MBX 1.57 Chassis
```

entity-manager `busctl tree` looks same as before the change.

No new warnings or errors found in `journalctl` output.
No new services failures on `systemctl --failed`
