iptables: abort on empty interface specification

Fiedler Roman brings to attention that if, in a faulty script,
"$some_variable" expands to an empty string, iptables should probably
catch this most likely undesired invocation. If no/all interfaces were
really desired, one can either omit -i completely, or use -i +.
