[PATCH v2] Fix missing /var/lib/dpkg/available in Buster rootfs

[PATCH v2] Fix missing /var/lib/dpkg/available in Buster rootfs

[Anton Mikanovich]

From: Vladimir Burkin <mxvisor@gmail.com>

When building an image based on Debian Buster the rootfs installation
fails on dpkg because /var/lib/dpkg/available is missing.
isar-mmdebstrap.inc tries to work around this by adding an mmdebstrap
hook. The hook uses touch /var/lib/dpkg/available, but it runs on the
host rather than inside the mmdebstrap rootfs. The proposed fix is to
use the hook parameter $1 (the mmdebstrap rootfs path) when creating
the file.

Hello Vladimir,

Thanks for submitting the patch.
I've resent your commit as v2 with some formatting applied.
Here is the way how we send patches for the review on the list:

- Send in text form (no attachments, no html allowed).
- Title should shortly describe the fix.
- Commit message should describe what is done and why it is done.
- Field Signed-off is required to point on commit authors.
- Field From is nice to have.
- Title ~50 symbols, commit message lines <72 symbols.

Sending the patch can be done from git itself by the command like:

git send-email -1 --subject-prefix="PATCH v2" --to 
isar-users@googlegroups.com

where:
-1 - send 1 commit from the HEAD of current repo.
--subject-prefix="PATCH v2" - version 2 of patchset, can be just "PATCH" 
for v1.
