Rename the macro in the KVM selftests to TEST_ASSERT_EQ to avoid the problem - it is also more similar to the other macros in test_util.h that way.

Let's make this a little bit more user-friendly and include some TAP output via the kselftest_harness.h interface. To be able to use the interface, we have to break up the huge main() function here in more fine grained parts - then we can use the TEST_F() macro to define the individual tests. Since these are run with a separate VM now, we have also to make sure to create the expected state at the beginning of each test, so some parts grow a little bit - which should be OK considering that the individual tests are more self-contained now.
