From: Geliang Tang <tanggeliang@kylinos.cn>

This patch includes net_helper.sh into mptcp_lib.sh, uses the helper
wait_local_port_listen() defined in it to implement the similar mptcp
helper. This can drop some duplicate code.

It looks like this helper from net_helper.sh was originally coming from
MPTCP, but MPTCP selftests have not been updated to use it from this
shared place.
