    yocto: Various misc cleanups to install scripts
    
    Add a new gnomeos-update-branches.sh script which just does the work
    of checking out roots.  This is useful if you e.g. make a local
    modification.
    
    Rename scripts to gnomeos-*.sh consistently.
    
    Tweak gnomeos-clone-qemu.sh script to support command line arguments
    (again).
