selftests: ovpn: check asymmetric peer-id

Extend the base test to verify that the correct peer-id is set in data
packet headers. This is done by capturing ping packets with tcpdump during
the initial exchange and matching the first portion of the header
against the expected sequence for every connection.

selftests: ovpn: add notification parsing and matching

To verify that netlink notifications are correctly emitted and contain
the expected fields, this commit uses the tools/net/ynl/pyynl/cli.py
script to create multicast listeners. These listeners record the
captured notifications to a JSON file, which is later compared to the
expected output.
