[syslinux-iso] Add PXE support via NBD.

nbd (network block device utilities) package is required.
This package is in AUR at this moment.
http://aur.archlinux.org/packages.php?ID=9691

Also added dnsmasq pkg, so the live-medium, appart of support booting from PXE
also add the capability to acts as server for PXE & NBD.

This is a dirty script to ilustrate how to launch server:

---- Cut here ----

IP=$1
ISO=$2

ifconfig eth0 ${IP}
dnsmasq \
  --enable-tftp \
  --tftp-root=/bootmnt/boot \
  --dhcp-boot=/pxelinux.0,"${IP}" \
  --dhcp-range=${IP%.*}.2,${IP%.*}.254,86400
nbd-server 9040 ${ISO} -r
---- Cut here ----
