defined zsuper: Handle NULL superclass for `BasicObject`
Prior to this commit, a segmentation fault occurred in `vm_defined`'s
`zsuper` implementation after NULL is returned as `BasicObject`'s superclass.
This fix returns false from `vm_defined` if the superclass is NULL.
For example, the following code resulted in a segfault.
```ruby
class BasicObject
def seg_fault
defined?(super)
end
end
seg_fault
```
