virtio tools uaccess primitives, pulling these in from <linux/compiler.h>.
With this done, we can kill off the now-unused ACCESS_ONCE() definition.

This makes them a bit more like the kernel headers, so we can include more
real kernel headers in our tests.
In addition this means that we don't break tools/virtio with the next
patch.
