[v8 04/14] meta: Use cached base-apt repo to bootstrap

[Aliaksei Karpovich <akarpovich@ilbers.de>]

From: Uladzimir Bely <ubely@ilbers.de>

This patch makes local base-apt repo to be created before
bootstrap task. So, bootstrap is then done from it.

The required packages are downloaded via python-apt and
reprepro creates debian-like repository from .deb files.

For debian targets host keyring is used while ubuntu/raspbian
targets use keys specified by DISTRO_BOOTSTRAP_KEYS variable.

The goal is have workable base-apt repo before first build completed.
