    hydra: Add configuration for giedi.
    
    This is a old Intel NUC that I've repurposed as a build machine. It's
    not particularly powerful, and I'm not sure how long the hardware will
    last for, but it's still more build hardware for
    bordeaux.guix.gnu.org, and adds some diversity given it's low core
    count.
