Phil Sutter 719f60bb91 utils: iptables: Use go-iptables' ChainExists()
Starting with v0.5.0, go-iptables exports a fast ChainExists() which
does not rely upon listing all chains and searching the results but
probes chain existence by listing its first rule. This should make a
significant difference in rulesets with thousands of chains.
