Use lrzip+tar instead of lrzuntar
Use lrzip+tar instead of lrzuntar

Extract docker images from archive using lrzip + tar instead of
single lrzuntar command. It should lower extraction times on a
weak hardware.

Also remove each container tarball right after loading it into
docker in order to reduce disk usage.
