Add support for multilib.

New parameter '-M' to the "make_slackware_live.sh" script will add
a squashfs module "0020-slackware_multilib-VERSION-ARCH.sxz" to the iso,
its contents based on the ./pkglists/multilib.* package repo definitions.
Only for the x86_64 architecture of course.

If you already have a USB Live, you can simply copy this module into the
directory "/liveslak/addons" to transform your pure 64bit Slackware Live
Edition into a multilib variant.
