mklive: improved to avoid host deps; use our own pkgs to generate images.

That means that mklive just needs xbps to generate working images.

Usage: mklive.sh [options]

Options:
 -r <repo-url>      Use this XBPS repository (may be specified multiple times).
 -c <cachedir>      Use this XBPS cache directory (/var/cache/xbps if unset).
 -k <keymap>        Default keymap to use (us if unset)
 -l <locale>        Default locale to use (en_US.UTF-8 if unset).
 -i <gzip|bzip2|xz> Compression type for the initramfs image (gzip if unset).
 -s <gzip|bzip2|xz> Compression type for the squashfs image (xz if unset)
 -o <file>          Output file name for the ISO image (auto if unset).
 -p "pkg pkgN ..."  Install additional packages into the ISO image.

The mklive.sh script generates a live image of the Void Linux distribution.
This ISO image can be written to a CD/DVD-ROM or any USB stick.
