eval.c: rename "rb_frozen_class_p" to "rb_class_modify_check"

Just refactoring.  Despite its name, the function does NOT return a
boolean but raises an exception when the class given is frozen.
I don't think the new name "rb_class_modify_check" is the best, but
it follows the precedeint "rb_ary_modify_check", and is definitely
better than "*_p".
