From: Jan Kiszka <jan.kiszka@siemens.com>

During the migration to sbuild, support for using self-built packages in
the build environment was lost if those were already part of the
sbuild-chroot. This restores it by adding --apt-distupgrade to the
sbuild call. But that is not enough because sbuild will only upgrade
packages from already configured sources, not those specified via
--extra-repository. We therefore have to switch back to configuring
isar-apt during sbuild-chroot creation.

As rootfs_configure_isar_apt configures the isar repo under
/isar-apt, we bind-mount the one in /home/builder/${PN} to that folder.
Another difference is that we now need to run apt-get update explicitly,
but only for isar-apt.

For apt fetching, we neither need nor want isar-apt to be available.
Rebuilding self-generated apt packages is generally pointless as the
needs are better addressed in the generating recipe itself. Exposing
isar-apt to the fetch may furthermore lead to fetching a previously
built source package of the same recipe, rather than pulling the
external version.

And because the sbuild-chroots are now left behind with isar-apt
configured, the configuration in imager_run can be removed (credits to
Srinuvasan Arjunan).

Thanks for sending - thought I did, but I only prepared locally, never
triggered the submission.
