Support PowerNV Qemu for running tests

We now run tests under both Mambo and QEMU PowerNV model.

Also added are scripts in opal-ci/ for building powernv model qemu.
Currently, this is not yet in upstream qemu, so we build from Ben's branch.

You can start using qemu along with/instead of Mambo by:
1) (cd ./opal-ci; sudo ./install-deps-qemu-powernv.sh; ./build-qemu-powernv.sh)
2) Pointing QEMU_PATH and QEMU_BINARY environment variables to appropriate
   qemu binary with powernv model

When building qemu ourselves, we build a *specific* known good tag from
the open-power tree. This should ensure that into the future existing test
scripts should continue to function.
