Doc/library/multiprocessing.rst:2736: Before version 3.5, bound or

Doc/library/multiprocessing.rst:2736: Before version 3.5, bound or
unbound methods could not be used directly
"Before version 3.5," doesn't seem to be necessary.

``.. versionchanged:: 3.5`` will be rendered as "Changed in version
3.5:" so the sentence could be changed to match that.

unbound methods could not be used directly
