podman: updates podman package

- add missing runtime depency catatonit
 - removed SELinux variant, add config option for it instead, I do not believe we need variant of EVERY SELinux support capable software
 - add config option for iptables firewall setup in default cni network config, otherwise skip iptables part (part of nftables transition, use cni-plugins-nft for nftables fw support or better; forget about cni fw completely, instead use openwrt's own as that way your rules for containers do not disappear on firewall restart)
