[RFC PATCH 06/11] tests/avocado: Add FreeBSD distro boot tests for ppc

[Nicholas Piggin]

FreeBSD project provides qcow2 images that work well for testing QEMU.
Add pseries tests for HPT and Radix, KVM and TCG.

Other architectures could be added so this does not get a ppc_ prefix
but is instead named similarly to boot_linux.

CC'ing Warner to check if it's okay for us to use these images and
any comments or suggestions. avocado tests have many Linux boots so we'd
do much better to expand test coverage by adding some other systems.
