There are a few fields in the agent-installer-utils Makeflle that were needed when doing a nested "podman run" in the appliance. These are no longer necessary since the appliance uses the registry binary directly and does not require the podman run.

Note that

--storage-driver vfs

is NOT one of the fields that can be removed. This is needed since the appliance still needs to do a "podman build" for the registry and removing this can result in errors like:

using mount program /usr/bin/fuse-overlayfs: fuse: device not found, try 'modprobe fuse' first
level=fatal msg=fuse-overlayfs: cannot mount: No such file or directory

Using the vfs storage driver is also consistent with how Konflux runs buildah to build the container image.
