phosphor-dbus-interfaces: remove unused PACKAGECONFIG

The libphosphor_dbus was previously used in native/nativesdk targets
in order to prevent the library from being built (and to only export
YAML).  This PACKAGECONFIG is no longer necessary.  Remove it to
simplify the recipe and the [eventually] the underlying repository.
