    Fix defect introduced 20200521T2005Z: mismounted cache
    
    For a
      debian-testing [bullseye] within centos within debian-stable [buster]
    chroot chain, commit 8054eeb9a738 of 20200521T2005Z mounted the
    innermost chroot's /var/cache/apt/archives/ on the intermediate
    chroot's /var/cache/bullseye/ but failed to mount the host's
    /var/cache/bullseye/ directory anywhere.
    
    This made 'install_centos.sh' take 45% longer (37m vs 25.5m) because
    it downloaded a complete debian system each time; lmi however built
    successfully, and all its tests passed. By mounting the host's
    /var/cache/bullseye/ directory to the centos chroot's directory of
    the same name, this change restores the former speed.
