Fix crash when allocating classes with newobj hook
We need to zero out the whole slot when running the newobj hook for a
newly allocated class because the slot could be filled with garbage,
which would cause a crash if a GC runs inside of the newobj hook.
For example, the following script crashes:
```
require "objspace"
GC.stress = true
ObjectSpace.trace_object_allocations {
100.times do
Class.new
end
}
```
