Subject: [PATCH net-next] selftests: net: move wait_local_port_listen to lib.sh
The function wait_local_port_listen() is the only function defined in
net_helper.sh. Since some tests source both lib.sh and net_helper.sh,
we can simplify the setup by moving wait_local_port_listen() to lib.sh.
With this change, net_helper.sh becomes redundant and can be removed.
