Subject: [PATCH] Debian KS: Initialize default /etc/fstab

To provide a unified view of initial filesystem setup, this moves code
from base_bullseye.yaml into the kickstarts where we manage the
partition and filesystem creation.

Currently in CentOS, we have scratch-lv mounted at /scratch. ostree
support code will automatically setup symlinks to {opt, mnt, media, srv,
root} as follows:

 media -> var/rootdirs/media
 mnt -> var/rootdirs/mnt
 opt -> var/rootdirs/opt
 root -> var/rootdirs/root
 srv -> var/rootdirs/srv

Since /scratch is not a "supported" filesystem for this activity, we
will still require a minor base_bullseye.yaml temporary fix to set up
this link. (See Depends-On)

A followup activity is required here to move /scratch to /var/scratch
and make sure that the StarlingX code base is aligned.

Test Plan:
PASS - Build ISO
PASS - Install ISO and verify initial filesystem mounts
PASS - Ansible bootstrap
PASS - controller unlock
