T4309: Conntrack ignore fix to handle interface any

Interface 'any' not expected in nft rules, it means that option
iifname shouldn't exist at all

set system conntrack ignore ipv4 rule 10 inbound-interface 'any'

table ip raw {
chain VYOS_CT_IGNORE {

		iifname "any" counter packets 0 bytes 0 notrack comment "ignore-10"
		return

}
}

Fix it
