Don't include the command name when comparing the error messages. "ip6tables" in nft mode uses "iptables" in it's error messages. E.g.: in nft mode: ip6tables -D POSTROUTING -s 1100:200::5/24 -j DROP iptables: Bad rule (does a matching rule exist in that chain?). same command in legacy mode: ip6tables -t nat -D POSTROUTING -s 1100:200::5/24 -j DROP ip6tables: Bad rule (does a matching rule exist in that chain?).

Closes containernetworking#544 The above issue describes a situation where using the bridge plugin with IPv6 addresses prevented `DEL` from working correctly. `DEL` seems to be failing in the body of `TeardownIPMasq` This arises because: * twice delete postrouting rules: `ipn.String()` `ipn.IP.String()` containernetworking#279 * we are using a version of go-iptables which is bugged for v6 PR github.com/coreos/go-iptables/pull/74 describes why this does not work. The error message is not being checked correctly. Using a later version of go-iptables means that * when the second `ipt.Delete` fails (this is okay) * we will correctly interpret this as an non-fatal error * `TeardownIPMasq` will not prematurely exit the method * `ipt.ClearChain` now can run * `ipt.DeleteChain` now can run This explains why this was working for v4 but not v6 Signed-off-by: toby lorne <toby@toby.codes>
