libfdt: Remove superfluous NUL character from overlay symbols
The symbol path already ends with a NUL character (something which is
actually checked by the code) and this NUL is included in
rel_path_len, so there is no need to add a second one.
This change fixes incorrect display in "fdt list /__symbols" after
applying an overlay with symbols.
