[issue21044] tarfile does not handle file .name being an int

> you can't overwrite a io.FileIO().name attribute

A FileIO instance uses a dict for 'name' (msg214670): 

    >>> vars(sys.stdin.buffer.raw)
    {'name': '<stdin>'}

    >>> f = tempfile.TemporaryFile()
    >>> vars(f.raw)
    {'name': 3}

The name is optional meta-information. If it gets deleted, the repr falls back on using the file descriptor:

    >>> f.raw
    <_io.FileIO name=3 mode='rb+'>

    >>> del f.raw.name
    >>> f.raw
    <_io.FileIO fd=3 mode='rb+'>
