[v8 07/14] testsuite: Set ISAR_PREFETCH_BASE_APT by default

[Aliaksei Karpovich <akarpovich@ilbers.de>]

From: Uladzimir Bely <ubely@ilbers.de>

This makes Isar use `base-apt` repo in different way. Any package
installation is done from `base-apt` repo which is prepopulated
from external mirrors.

This behaviour is disabled by default for downstreams. To enable it,
set the variable to "1", like isar does in local.conf.sample.

In order to be able to run CI in old mode, allow CI read the option
from the environment. Also, adjust some tests (like repro one) to
make them work with ISAR_PREFETCH_BASE_APT set.
