addons: Update Inspektor Gadget entrypoint and cleanup.

Inspektor Gadget container entrypoint and cleanup programs were translated from
bash to golang [1, 2].
Upstream YAML file used to deploy was updated to reflect this change [3].

Sadly, it was not the case for the YAML used to deploy the minikube addon which
leaded to troubles [4, 5, 6].

The present commit updates the minikube addon YAML to use the correct programs
as entrypoint and cleanup.
