update service name for UPDATESERVICE_USE_DBUS

Update the Dbus service name and path for
BMCWEB_REDFISH_UPDATESERVICE_USE_DBUS. As part of updated implementation
the new BMC code updater daemon name is
xyz.openbmc_project.Software.Manager, update setActiveImage and
FactoryReset flows to reflect so.

Tested:
