Exercise virtio-fs for ppc64

[mopsfelder]

@farosas can provide details on how to build and test.

There is a CI repo: https://gitlab.com/virtio-fs/virtio-fs-ci

I have ensured it works with the development branches of QEMU/kernel (virtio-fs-dev on gitlab), but it might have drifted already. I can help get it back into shape once we have some kind of environment on where to run this.

Ideally we would run two jobs, one for each branch (virtio-fs, virtio-fs-dev). Each job consists of cloning QEMU and guest kernel repos, checking out the appropriate branch and running the CI scripts mentioned above which will build the components and run a simple test.

Let me know if any issues arise.

Note: I'm not against running any other set of tests, as long as the virtio-fs setup is present, I'm mentioning the virtio-fs-ci repo because it seems to be the simpler way to get this setup quickly.

Thanks
