runsc: Run sandbox as user nobody.
When starting a sandbox without direct file or network access, we create an
empty user namespace and run the sandbox in there. However, the root user in
that namespace is still mapped to the root user in the parent namespace.
This CL maps the "nobody" user from the parent namespace into the child
namespace, and runs the sandbox process as user "nobody" inside the new
namespace.
