scons: Make the sim_objects parameter of SimObject mandantory.
If there really are no c++ sim_objects in the file, then sim_objects can
be set to [] which it used to default to.
This way, if someone hasn't remembered to update their SConscript files
for the new sim_objects and enums parameters, this will give them some
indication what's wrong, rather than the build just failing later.
