Fix getManagedObjects on ObjectManager returning no objects

Currently, when calling getManagedObjects
```
busctl call xyz.openbmc_project.Time.Manager \
  /xyz/openbmc_project/time/bmc \
  org.freedesktop.DBus.ObjectManager \
  GetManagedObjects
```
we end up getting no objects `a{oa{sa{sv}}} 0`. This is incorrect
and we technically should return the managed objects.
Looking further at the spec:
```
All returned object paths are children of the object path implementing
this interface, i.e. their object paths start with the ObjectManager's
object path plus '/'.
```
This implies that the the path owned by the object manager should
not be the bmc sub-entries but `/xyz/openbmc_project/time`
