[PATCH v3 0/3] Don't update apt database on every package build

[Uladzimir Bely <ubely@ilbers.de>]

Here we want to avoid the default behaviour of sbuild when it tries
to update all apt sources.

To have package database consistent, we should rely on one we got
during the debootstrap. The only repo that really needs updates
is local `isar-apt` where custom build depends may be placed.

Also, `isar-apt` should have the high priority over other sources
and allow downgrades (like it was done earlier for buildchroot).

Changes since v2:
 - Allow downgrades when installing package dependencies

Changes since v1:
 - Disable only `apt update`, but leave `apt distupgrade` unchanged
(enabled by default). This allows package upgrades from isar-apt repo.
 - Added a patch that sets high priority for isar-apt.
