Only translate ModuleNotFoundError exceptions

require_tooling_dependency() now only translates
ModuleNotFoundError when the missing module is the
requested top-level package. Other import
failures are re-raised unchanged.

This helps in situation where third-party dependency
is installed but broken for whatever reason. Previously
we would intercept it and suggest to run
pip install cuda-bench[tools], but that was already done.
