common: Add emit_added for Software Update intf

The 'InterfacesAdded' signal is needed for the object mapper to know of
the dbus interface.

```
root@s8030-bmc-30303035c0c1:~# busctl tree xyz.openbmc_project.Software.BIOS
`- /xyz
  `- /xyz/openbmc_project
    `- /xyz/openbmc_project/software
      `- /xyz/openbmc_project/software/HostSPIFlash_5592
```

But the object mapper does not find the object path

```
busctl call xyz.openbmc_project.ObjectMapper /xyz/openbmc_project/object_mapper xyz.openbmc_project.ObjectMapper GetSubTreePaths sias /xyz/openbmc_project 0 1 xyz.openbmc_project.Software.Update
as 2 "/xyz/openbmc_project/software/269f96b7" "/xyz/openbmc_project/software/bios_active"
```

meanwhile it finds the version interface, since there we already emit
the signal.

```
busctl call xyz.openbmc_project.ObjectMapper /xyz/openbmc_project/object_mapper xyz.openbmc_project.ObjectMapper GetSubTreePaths sias /xyz/openbmc_project 0 1 xyz.openbmc_project.Software.Version
as 7 "/xyz/openbmc_project/logging/entry/1" "/xyz/openbmc_project/logging/entry/2" "/xyz/openbmc_project/logging/entry/3" "/xyz/openbmc_project/logging/entry/4" "/xyz/openbmc_project/software/269f96b7" "/xyz/openbmc_project/software/HostSPIFlash_5592" "/xyz/openbmc_project/software/bios_active"
```

Tested: Since the interface is emitted, object mapper now knows of the
object path.

```
busctl call xyz.openbmc_project.ObjectMapper /xyz/openbmc_project/object_mapper xyz.openbmc_project.ObjectMapper GetSubTreePaths sias /xyz/openbmc_project 0 1 xyz.openbmc_project.Software.Update
as 3 "/xyz/openbmc_project/software/269f96b7" "/xyz/openbmc_project/software/HostSPIFlash_2523" "/xyz/openbmc_project/software/bios_active"
```

The software appears as updatable in the fw inventory.

```
