    Correct package selection during upgrade-start-pkg-extract

    During upgrade-start we call upgrade-start-pkg-extract to extract the
    kickstarts and pxeboot data from the N+1 load. This data is used to boot
    controller-1 in duplex environments. As these packages can be patched we
    need to select the latest version of the package.

    Currently the dnf repoquery call returns every version of the rpm
    queried. This results in the base version being used during the package
    extraction. This commit updates the command to use --latest-limit=1.
    The command is also updated to use --disablerepo=*. This will result in
    the command being restricted to the specified N+1 repos. Without the
    disablerepo option the N repo packages are included in the results.

    This brings the call in line with the behavior of
    utilities/utilities/platform-util/scripts/gen-bootloader-iso.sh

    Testing:
    AIO-DX upgrade with patched kickstart package
