[PATCH 1/2] build: also use libtool for install stage

[Jan Engelhardt <jengelh@inai.de>]

The just-built library has DT_RPATH entries to be runnable from
whereever it is. If we just install that, the distro build systems
will throw warnings like

	(Open Build Service) ERROR: RPATH
	"/home/abuild/rpmbuild/BUILD/iptables-1.4.17a/libxtables/.libs"
	on /home/abuild/rpmbuild/BUILDROOT/iptables-1.4.17a-0.x86_64/usr/lib64/xtables/libxt_unclean.so
	is not allowed

These RPATH entries are indeed undesired for libraries is in a system
location, which is why libtool produces another copy of the library on
installation. The makefile however missed using libtool during
installation (introduced with commit v1.4.17-1-g68e77a2).
This patch now resolves this.
