* etc/guix-daemon.cil.in (guix_daemon): Specify more permissions for
guix-daemon to account for daemon updates and newer SELinux.
I can't promise that this is a complete list of everything that guix-daemon
needs, but it's probably most of them. It can search for, install, upgrade,
and remove packages, create virtual machines and containers, update itself,
and so on.
