tests: add %NOLISTENPORT and use it

The purpose with this variable is to provide a port number that is
reasonably likely to not have a listener on the local host so that tests
can try connect failures against it. It uses port 47 - "reserved"
according to IANA.

Updated six tests to use it instead of the previous different ports.

Assisted-by: Emil Engler
Closes #5270
