Centos7 is a bit more opinionated on how git-daemon should run. In
particular with selinux the git_system_t context does not have
permissions to the git_port_t port(s) because systemd is expected to do
socket activation for git-daemon.
Fix this by not fighting systemd and embracing it. Use it for socket
activation with the git-daemon process and potentially add the git
daemon port to git_port_t label if necessary.
