  system-ovn.at: Make tests more portable.

Due to slight differences in behavior and/or output of some of the
utilities used by the tests when run on different distributions some
tests were failing, e.g., when run on Ubuntu 20.04.

Use "tcpdump -nn" to avoid host and port resolution;  also update "nc"
usage to avoid options that behave differently on various distributions.

This commit adds no guarantee that tests will pass on all possible
distributions, only tested on: Fedora 32 and Ubuntu 20.04.

  ci: Enable OVN system tests in GitHub Actions runs.

For now only enable system tests using the kernel datapath.  Running
the system tests with the userspace datapath makes some tests fail
due to known issues in the OVS userspace conntrack implementation which
are actively worked on.

To save CI time, only enable system test runs for a single item in the
test matrix ("linux gcc system-test").

We're also moving to Ubuntu 20.04 LTS in CI to avoid hitting:
