dup_and_fixup_symbol_prop() rewrites a symbol value by replacing its
"/fragment/__overlay__" prefix with the fragment's target path. When
the fragment targets the root node the target path is "/" and the
result starts with "//", which __of_find_node_by_full_path() cannot
resolve: symbols pointing into such fragments silently stop
resolving.
Drop the target path when it is the root and the tail is non-empty. A
value naming the fragment root itself (empty tail) keeps the "/".
