selftests: netfilter: Fix and review rpath.sh
Address a few problems with the initial test script version: * On systems with ip6tables but no ip6tables-legacy, testing for ip6tables was disabled by accident. * Firewall setup phase did not respect possibly unavailable tools. * Consistently call nft via '$nft'. Fixes: 6e31ce831c63b ("selftests: netfilter: Test reverse path filtering") Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
