systemctl: update 'show' format for socket units

Before this.
```
$ systemctl show systemd-journald.socket | grep Listen
ListenStream=/run/systemd/journal/stdout
ListenDatagram=/run/systemd/journal/socket
$ systemctl show --property ListenStream systemd-journald.socket
$ systemctl show --property ListenDatagram systemd-journald.socket
$ systemctl show --property Listen systemd-journald.socket
ListenStream=/run/systemd/journal/stdout
ListenDatagram=/run/systemd/journal/socket
```

After this.
```
$ systemctl show systemd-journald.socket | grep Listen
Listen=/run/systemd/journal/stdout (Stream)
Listen=/run/systemd/journal/socket (Datagram)
$ systemctl show --property Listen systemd-journald.socket
ListenStream=/run/systemd/journal/stdout
ListenDatagram=/run/systemd/journal/socket
```

Fixes #8064.
