This might be useful to watch the amount of built and selected
packages and some progress about it. So added python script which
prints progress and build stats. The sample of output is:

Press Ctrl-C to exit ...

Building: output/qemu_x86_64

RFC v2:
    1) filter rootfs package type
    2) rename build-progress -> show-progress
    3) check empty version
