There's no need to warn about the firewall when parsing, because the unit might not be started at all. Let's warn only when we're actually preparing to start the firewall. This changes behaviour: - the warning is printed just once for all unit types, and not once for normal units and once for transient units. - on repeat warnings, the message is not printed at all. There's already detailed debug info from bpf_firewall_compile(), so we don't need to repeat ourselves. - when we are not root, let's say precisely that, not "lack of necessary privileges" and "the local system does not support BPF/cgroup firewalling". Fixes #12673.
