[PATCH 5/5] build: build only iptables-multi

[Jan Engelhardt <jengelh@medozas.de>]

I see no pressing reason to install all single programs when the
multi binary can do the job. Within the build directory, developers
can run the components by means of, for example,

	./ip6tables-multi {main|restore|save} ...

And when make install-ed, symlinks are available.
