Test: add check using netstat.

Sometimes we see regression errors like:
2024-12-01 13:55:55.508: watchdog pid 27340: FATAL:  failed to create watchdog receive socket
2024-12-01 13:55:55.508: watchdog pid 27340: DETAIL:  bind on "TCP:50002" failed with reason: "Address already in use"

Before starting each regression test, we use "clean_all" script to
kill all remaining process.  I suspect that this is not enough to
release bound ports. So I add netstat command to check whether some
ports are remain bound.

For not this commit is master branch only.
