Hard-coded service name replaced with call to ObjectMapper

In the openbmc code, the dbus service name is hardcoded.
The ObjectMapper provides a way to find out the service name by
issuing a GetObject method call to the ObjectMapper.
That functionality is implemented in mapper.c
The output of the call to the mapper is a service name.

Resolves openbmc/openbmc#319.
