    Invoke the correct gen-bootloader-iso.sh script based on distro

    The gen-bootloader-iso.sh script for CentOS was renamed and invoked in
    previous commits to utilities [1] and distributedcloud [2] repos.
    However, the renamed script was not packaged and installed
    resulting in subcloud deployment failure in CentOS based StarlingX.

    The issue is resolved by
    https://review.opendev.org/c/starlingx/utilities/+/853023 and this commit.

    [2] https://review.opendev.org/c/starlingx/distcloud/+/851679

    Test Plan:
       - Verify successful subcloud deployment in CentOS
       - Verify proper cleanup of shared and subcloud specific boot files
         post remote install
