This:

1. Removes the `reportUniqueWarning` overload that accepts `Error Err`.

We can live with the version that accepts `const Twine &` and
anyways warnings reported in many places touched by this patch can probably
be improved. To do that we would need to use `Twine` version anyways.

2. Converts the last `reportWarning` in `ELFDumper.cpp` to `reportUniqueWarning`.

In that place it is a no-op I believe.
