Subject: [PATCH] Add IOBase to types fcntl will accept as files (#1556)

* Remove unused typing import from stdlib/3/fcntl.pyi

* Add IOBase to types fcntl will accept as files

Anything that implements a fileno() method is acceptable (per
https://github.com/python/cpython/blob/master/Objects/fileobject.c#L168-L173),
and IOBase fits the bill.

Fixes #1548.
