Thanks for catching this! I completely forgot to add the import.

For context to others, the relevant line is
216          assert isinstance(spec.loader, importlib.abc.Loader)
which was added by me in commit 52a5d80a2225 ("kunit: tool: fix
typecheck errors about loading qemu configs").

We could potentially add a Fixes: tag on this, but this looks good to me.
