extensions: avoid a crash when the version isn't properly byteified on py3

We already force bytestr on the `testedwith` and `buglink` attributes in
dispatch.py when generating a bug report with a similar comment about not
every extension being ported to py3.  We should do the same here, so the
function can be properly typed.
