Fix T48416: Impossible to copy a linked object from a file to another one mantaining the linked library.

When writing temp blenbuffer file, libraries of linked datablocks where not tagged correctly, which
means they were not put in the temp Main used to write the buffer, resulting in implicit localization
of linked data.
