lguest: fix failure to find linux/virtio_types.h

We want to use the local kernel headers, but -I../../include/uapi leads us into a world of hurt. Instead we create a dummy include/ dir with symlinks. If we just use #include "../../include/uapi/linux/virtio_blk.h" we get: ../../include/uapi/linux/virtio_blk.h:31:32: fatal error: linux/virtio_types.h: No such file or directory #include <linux/virtio_types.h> Signed-off-by: Rusty Russell <[email protected]>
