Title:
  lb_chroot_dpkg doesn't check dpkg version before setting 'unsafe-io'
  option

Status in “live-build” package in Ubuntu:
  New
Status in “live-build” package in Debian:
  Unknown

Bug description:
  The dpkg in the chroot (on a lucid build for example) might not be new
  enough to handle the 'unsafe-io' option set in the configuration file.

  lb_chroot_dpkg should check the chroot's dpkg capability first, e.g.

  Chroot chroot dpkg --force-help | grep -q unsafe-io
