convert: stringify `shlex` class argument

The documentation is handwavy, but typeshed says this should be `str`[1].  I'm
not sure if this is the correct encoding (vs `fsencode` or "latin1" like the
tokens returned by the proxy class).

While we're here, we can add a few more type hints that would have caused pytype
to flag the problem.
