scripts: size_report: Don't set non-terminal node address

Don't set 'address' property for non-terminal nodes which are
also shown in JSON footprint reports, thus to avoid confusion
that a file or directory node has a continuous memory area allocated
at some address and with the total size of all its associated child
nodes which are likely scattered over different memory sections.
