xtables-compat: xtables-save: don't return 1

noticed that iptables-compat-save exits with 1 on success,
whereas iptables-compat-save -t filter returns 0 (as expected).

Caused by double-invert of return value, so ge rid of those.
do_output now returns a value suitable to pass to exit() or return from main.
