cpplint: Ignore some casting warnings

In both cases, the warning is about a function argument that we do not use.
There's no benefit of doing a c++-style cast there, especially since they're
function arguments. In fact, doing anything else would just make the code less
readable. As such, we opt to ignore these warnings instead.
