Use LXC_ROOTFS_MOUNT in clonehostname hook

Previously this hook did not work when cloning containers using an overlayfs snapshot as the LXC_ROOTFS_PATH didn't point to the actual filesystem that the container would see. LXC_ROOTFS_MOUNT should be used instead and in fact lxc.container.conf man page says that you usually would want to use the _MOUNT variant. Signed-off-by: Matt Keeler <mjkeeler7@gmail.com>
