patch-iso: Secondary ISO input

To generate the pre-patched ISO, take some content
from a secondary input ISO.

Specifically, all ISO content should be taken from 24.09 GA,
expect for the "patches", "kickstart" and "upgrades" folders.

The ostree_repo remains the same as it is, being taken
from "ostree_base"

Test Plan:
pass - Mock pipeline
