class.c: check for malloc failures

• class.c (rb_class_subclass_add): use xmalloc
• class.c (rb_module_add_to_subclasses_list): ditto
• class.c (rb_class_remove_from_super_subclasses): use xfree
• class.c (rb_class_remove_from_module_subclasses): ditto
  [Bug #9616]

xmalloc does OOM checking and helps GC accounting when used
with xfree.
