Correct the emission of meta class ivars.

type_obj_class is no longer a class, so its ivars are not stored in
type_obj_class.t.class->ivars but rather type_obj_class.t.symtab.

This fixes the segfault Spirit and Randy were experiencing.

In passing, correct the unneeded emission of meta class ivars for non-root
classes. This should make for much smaller progs that use classes.
