libfdt: fdt_path_offset_namelen: Reject empty paths

Make empty paths result in FDT_ERR_BADPATH.

Per the specification (v0.4-rc4):

> The convention for specifying a device path is:
>     /node-name-1/node-name-2/node-name-N
>
> The path to the root node is /.
>
> A unit address may be omitted if the full path to the
> node is unambiguous.
