vfs: ensure closewrapbase fh doesn't escape by entering context manager
I'm not sure if there's a problem in practice here, as there's no test failure
either way. The __exit__() and close() methods raise an exception, so maybe
__exit__() and close() are being called directly on the underlying handle when
delayclosedfile is used on a context manager? I doubt that was intended.
