[PATCH] isar-bootstrap-helper: Purge /var/lib/apt/lists on cleanup

[Jan Kiszka]

This saves dozens of MB on the target image. The user just needs to run
"apt-get update" to restore it.

The lowest hanging fruit for tinyfication. Base image on armhf, e.g., is
now ~100 MB.

Claudius, to my understanding, this will not break reproducibility as
--clean is only done on the final target image, not during the build,
not on the buildchroots.

I don't think so. And if it does then it should be possible to avoid
it.
