[archiso] Add archiso_shutdown hook.

STATUS: Working (std boot, loop_mnt, pxe) with copytoram=[y|n].

NEEDS: initscript > 2011.07.3, mkinitcpio > 0.7.2, mkinitcpio-busybox > 1.18.5-1

Purpose: we need this for propertly unmount $cow_device,
used for persistent dm-snapshot devices.

This hook is based on work from Tom Gundersen[#1],
but adapted for archiso things (specially the shutdown script)
