[kvm-unit-tests PATCH v2] travis.yml: Test with KVM instead of TCG (on x86)

[Thomas Huth <thuth@redhat.com>]

Travis nowadays supports KVM in their CI pipelines, so we can finally
run the kvm-unit-tests with KVM instead of TCG here. Unfortunately, there
are some quirks:

First, /dev/kvm is not accessible on Ubuntu by default. You have to be
"root" or in the "kvm" group to access it. But changing the group of the
current user is not taking into account for the current shell process, so
that would need some indirections in the yml file. Thus the yml script now
rather changes the group and "g+s" permission of the qemu binary instead.

Second, not all x86 tests are working in this environment, so we still
have to manually select the test set here (but the amount of tests is
definitely higher now than what we were able to run with TCG before).

 v2: Use chgrp + "chmod g+s" instead "chmod u+s" to get it running
