Subject: py/emitnative: Cancel caught exception once handled to prevent
 reraise.

The native emitter keeps the current exception in a slot in its C stack
(instead of on its Python value stack), so when it catches an exception it
must explicitly clear that slot so the same exception is not reraised later
on.
