tests/functional: Convert simple avocado tests into standalone python tests

These test are rather simple and don't need any modifications apart
from adjusting the "from avocado_qemu" line. To ease debugging, make
the files executable and add a shebang line and Python '__main__'
handling, too, so that these tests can now be run by executing them
directly.
