Minor, workaround an incremental compilation issue

After the previous commit, IC does not recompile code related to CLI
arguments parsing (likely due to KT-57919), so the resulting dist
compiler doesn't work at all, and all related tests are failing. This
"useless" override tricks the IC to recompile the class and all its
subclasses.
