Subject: [PATCH] Pull only the latest ostree commit to pre-patched ISO

This commit change the patch-iso-debian script to pull only the latest
ostree commit from the repository used to create it. This make the iso
not increase in size exponentially.

Test plan:
PASS: Create ISO using the script.
PASS: Check if ostree_repo/ contains only the latest commit.
PASS: Install AIO-SX system.

Closes-Bug: 2046811
