support/testing: TestIptables: check for netfilter legacy tables enabled

Browse Source 
TestIptables expect netfilter legacy tables enabled in the kernel.

Make sure we use iptables-legacy:

  iptables --version
  iptables v1.8.11 (legacy)

The test would fail if nftables compat (iptables-nft) is enabled.

  iptables --version
  iptables v1.8.11 (nf_tables)

Add the following configuration fragment to enable iptables-nft:

  BR2_PACKAGE_IPTABLES_NFTABLES=y
  BR2_PACKAGE_IPTABLES_NFTABLES_DEFAULT=y
