scripts: west_commands: core: run netcat with check_call()

Netcat (nc) does not handle SIGINT. It silently ignores it.

We cannot use run_client(), given that the pydoc for
run_client() specifically contains "Run a client that
handles SIGINT".

Instead, use check_call(), which correctly handles Ctrl+C.
