chromeos-dbus-bindings: Ignore multi-return methods
Multiple return arguments are legal in D-Bus. Instead of throwing
a fatal error, ignore methods of this sort in the adaptor
generator, since libchromeos currently cannot automatically
generate returns for such methods.
While here, provide a protected getter to the DBus interface
pointer, so subclasses can register their own methods.
