app-emulation/libvirt: tweak libvirt-guests init script

After discussing the new init script on bug #558034 there are two tweaks
being added:
* shift the first argument so that future uses can pass in more arguments
  to virsh and the wrapper commands.
* Added LIBVIRT_IGNORE_AUTOSTART to ignore domains that start marked for
  autostart in the libvirt XML.
