    sysutils/skopeo: fix source build when git binary is present
    
    If git is present, go will attempt to extract the version from the ports
    git repo, which is not the git repo of skopeo itself. explicitly block
    the discovery mechanism.
    
    $ skopeo -v
    skopeo version 1.20.0 commit: "unknown"
