[v3,20/24] tests/functional: Convert the ppc_hv avocado test into a standalone test

From: Thomas Huth <thuth@redhat.com>

Note: The original Avocado test seems currently to be broken, it hangs
when the guest is trying to install additional packages. So mark it as
broken for now until it gets fixed.

 rename tests/{avocado/ppc_hv_tests.py => functional/test_ppc64_hv.py} (88%)
 mode change 100644 => 100755

Thanks for doing this.

I have a fix for this problem, it's a bug with the test harness
code but was not merged yet. I'll re-send it.

Thanks,
Nick
