Generate Kube should not print default structs

If podman uses Workdir="/" or the workdir specified in the image, it
should not add it to the yaml.
If Podman find environment variables in the image, they should not
get added to the yaml.

If the container or pod do not have changes to SELinux we should not
print seLinuxOpt{}

If the container or pod do not change any dns options the yaml should
not have a dnsOption={}

If the container is not privileged it should not have privileged=false
in the yaml.

Fixes: https://github.com/containers/podman/issues/11995
