iptables-restore/save: exit when given an unknown option
When an unknown option is given, iptables-restore should exit instead of continue its operation. For example, if `--table` was misspelled, this could lead to an unwanted change. Moreover, exit with a status code of 1. Make the same change for iptables-save. OTOH, exit with a status code of 0 when requesting help.
