   libxt_CONNMARK: use guided option parser

BTW, I think it would be good if we find the way to check for
libxtables current version (see iptables/configure.ac), so you can
know that we broke binary compatibility again.

For the C level, there is XTABLES_VERSION_CODE.

#if XTABLES_VERSION_CODE >= 6
	if (m != NULL && m->x6_parse != NULL)
		m->x6_parse(...)
#else
	else if (m != NULL && m->parse != NULL)
		m->parse(...)
	...

We can also export this through pkgconfig, similar to how
downstream users are to discover the plugin dir
(`pkg-config xtables --variable libdir`).
