[PATCH iptables v3] xtables-translate-restore: do not escape quotes

["Pablo M. Bermudo Garay" <pablombg@gmail.com>]

If quotes are escaped, nft -f is unable to parse and load the translated
ruleset.

Changes in v3:
  - Add a new field to the iptables_command_state struct instead of
    propagate 'bool restore' argument.
