[PATCH v8 3/8] meta: Fix missing dpkg available

[Anton Mikanovich <amikan@ilbers.de>]

In some distros /var/lib/dpkg/available is required for
do_rootfs_install task.
The fix for it is present in jessie-or-older mmdebstrap hook in
Bookworm and later, but maybe-jessie-or-older wrapper do not handle
distro version check correctly.
That's why we need to check and apply hook manually or create
/var/lib/dpkg/available by hand for older distros.
