json.load doesn't properly forward array_hook to json.loads

Bug report

The recently introduced array_hook parameter to json.load isn't being forwarded to json.loads, making it a no-op (it is always None).

This very simple reproducer shows it -- it fails with an Assertion Error.

fp = StringIO('[10, 20, 30]')
result = self.json.load(fp, array_hook=tuple)
assert isinstance(result, tuple)
