feat: report what listens, and which procd service it is

Mixes in napalm-device-types' ListeningSocketsMixin (2.5.0): without ss
the shared command reads busybox netstat, and each process's cgroup names
its procd service. The driver only carries the command across.

Over an SSH exec channel of its own, not the interactive shell: busybox
ash cuts a typed line at 512 characters, the command is longer, and the
cut line left the shell waiting for a closing quote. OpenWrt logs in as
root; a login other than root cannot become root, so its reading says it
is not attributed.

Checked against a real OpenWrt 25.12.2 access point. For netOrk#673.
