Currently the tests at the end of the .travis.yml script are ignored,
since we can not use KVM in the Travis containers. But we can actually
run of some of the kvm-unit-tests with TCG instead, to make sure that
the binaries are not completely broken.
Thus introduce a new TESTS variable that lists the tests which we can
run with TCG. Unfortunately, the ppc64 and s390x QEMUs in Ubuntu also
need some extra love: The ppc64 version only works with the additional
"cap-htm=off" setting. And the s390x package lacks the firmware and
refuses to work unless we provide a fake firmware file here. Any file
works since the firmware is skipped when "-kernel" is used, so we can
simply use one of the pre-existing files in the source tree.

What about the other s390x tests? (is the QEMU binary too old to make
them pass?)
The issue with TCG is that you can easily get false negatives in case
the QEMU binary changes (e.g., new Ubuntu release).
"to make sure that the binaries are not completely broken" - while I
understand the intuition behind that, I wonder if this is relevant in
practice (especially, somebody committing changes without testing them,
especially, under KVM). As long as the false negatives here don't hurt,
I guess this change is fine.

Yes. All the others are failing.

That should not be a big deal, since the Ubuntu version is locked to a
certain release in the travis.yml file. So we should not get a new
version of QEMU by accident here, only if we explicitly update the
"dist:" line in the yml file.

Well, the test coverage here is certainly far from being perfect, but
it's still better than nothing. Imagine one of the patches changes
common code in the lib/ folder and it only works on one architecture
that the author tested. Chances are quite good that we detect that
problem with this patch now.

So the QEMU versions is that old that not even the selftest works? :/ Is
there a more recent distribution we can use?

Or if the dist updates QEMU. Not sure how often that happens in QEMU.

I already tested with "dist: bionic", and that's all I've got to get
working there. According to
https://docs.travis-ci.com/user/reference/overview/ there are no newer
distros available yet.

I don't think that they will update the QEMU version during the
life-cycle of a certain release - they likely only apply some bug fixes,
which won't change much of the behavior here. Remember that
qemu-system-s390x is almost completely broken in these Ubuntu versions
since they do not ship the firmware image in the package. I only got
something running by luck with that "firmware=..." trick.
