Solution is to upgrade git to version 2.

[root@localhost block-box]# yum install https://centos7.iuscommunity.org/ius-release.rpm && yum swap git git2u

[root@localhost block-box]# make blockbox
docker build https://git.openstack.org/openstack/loci.git \
    --build-arg PROJECT=cinder \
    --build-arg FROM=centos:7  \
    --build-arg PROJECT_REF=master \
    --tag debian-cinder:latest
