kernel: Enable virtio-fs in kata kernel

This patches adds virtio-fs capability to the kata kernel along with
config changes to enable the same on kata by default. The system will
only be exercised when `shared_fs` is set to `virtio-fs` in the kata
configuration file. the default still remains to be 9p

Fixes: kata-containers#387
Depends-on: github.com/kata-containers/runtime#1016
