libcontainer: copy_minor: Do not fail when host device does not exist
It is useful to be able to specify -1 as minor number in runtime.json,
so that the minor number is copied from outside the container.
However, the device may not exist outside of the container, in that case,
just skip it and not create it inside the container.
