Tests: Ensure binding on localhost host is consistently ipv4/v6 

The current netty multiport tests bind on localhost and then try to connect
to 127.0.0.1, which may fail, if localhost is resolved to ipv6 by default.

This randomly chooses between 127.0.0.1, localhost and ::1 (if available) for
binding and then uses this throughout the test.
