sd-bus: when credentials of the "org.freedesktop.DBus" service are queried return the bus owner's credentials

Browse Source 
The bus driver service is always implemented by the owner of the bus,
hence let's shortcut the credential operation and use our cached data.
This makes sure things simply work, given that dbus itself doesn't
support GetConnectionSELinuxSecurityContext() on the bus driver name
itself.
