This is only a soft loop.
pve-firewall can be compiled and used without qemu-server and without
pve-container as it includes these packages only if they exist, it's not
a hard dependency. It's a hard dependency the other way round:
qemu-server makes use of methods from PVE::Firewall to deal with the
firewall configuration/api.
