subcloud install fails in gen-bootloader-iso.sh when using dev-built loads

[Kyle MacLeod]

Brief Description

Unable to install subclouds using a dev built load. The gen-bootloader-iso,sh fails as it can't find the signature file from the custom dev-built ISO image

Severity

Major - this impacts developers who need to test installs in a DC env before merging their code

Steps to Reproduce

    Build a dev ISO
    Install the ISO on system controller and subclouds

Expected Behavior

subclouds are able to install successfully

Actual Behavior

subclouds fail to install

Reproducibility

Reproducible

Workaround

Replace gen-bootloader-iso.sh with the version before https://review.opendev.org/c/starlingx/utilities/+/899432 allowed the install to proceed (testing still in progress)

    Fix initrd-mini extract for dev builds

    Developer builds do not have the initrd-mini{,.sig} in their
    ostree repo. This commit allows for the missing files to be taken
    instead from from the original /var/miniboot location.

    Test Plan

    PASS: Perform remote install for a developer-built ISO. Ensure the
    gen-bootloader-iso.sh script uses the /var/miniboot/initrd-mini{,.sig}
    files and is able to install the subcloud.
