This is a more throughout attempt to ONLY use the host apt to assemble
the rootfs. The key idea is to behave similar to mmdebstrap:
Use the host apt for all apt operations, but run dpkg inside the chroot.
This also allows us (part of this series), to not have apt at all in the
generated rootfs. If needed, users can just include it via
IMAGE_PREINSTALL += "apt".

The series is still in quite an early state and does not support the
base apt yet. As the base-apt is anyways currently being reworked, I
do not plan to support it as part of this series.

Review comments are highly welcome.

Best regards,
