kata-deploy: Allow shim creation based on what's passed to the daemonset

Instead of hardcoding shims as part of the script, let's ensure we can
allow them to be created based on environment variables passed to the
daemonset.

This change brings no functionality change as the default values in the
daemonset are exactly what has been used as part of the scripts.

Fixes: #7407
