obmc-console: Consolidate handling of default socket-id

If console-id is not specified on command line or in the config file
then use the default value. ae2460d0b8e8 ("obmc-console: Provide a
default value for `console-id`.") only implemented the default value for
naming the abstract listening socket and overlooked the new DBus path
naming convention.  This caused issues during dbus registration:

```
obmc-console-server: Object name: /xyz/openbmc_project/console/(null)
obmc-console-server: Failed to issue method call: Invalid argument
```

Fixes: ae2460d0b8e8 ("obmc-console: Provide a default value for `console-id`.")
