On linux sockets have a really good, unique identifier, the SO_COOKIE, which is used by sockdiag and BPF and elsewhere. Let's expose this more prominently in the service name of per-connection services invoked via Accept=yes sockets. This is really nice, because together with our $SO_COOKIE env var we can now match up services, process execution contexts, and "ss" outputs, BPF rules, and more.
