[PATCH v3 2/3] sbuild: Set high prio for the packages from isar-apt repo

[Uladzimir Bely <ubely@ilbers.de>]

This sets high priority for `isar-apt` repo during sbuild session.
So, even if some dependency in other repos has higher version than
one we previously built and placed in isar-apt, the second one wil
be selected.

This repeats the behaviour that is implemented in rootfs.bbclass
via `rootfs_configure_isar_apt` that is disabled for sbuild chroot.

We can't simply enable this task for sbuild while we don't want to
have `/etc/apt/sources.list.d/isar-apt.list` file in sbuild chroot
while it's handled via sbuild by `--extra-repository` option
