loader: fix d-tor call order

In the case when there are multiple dependencies on
the same library in the local_group the unload may
in some situations (covered now by tests) result
calling d-tors for some libraries prematurely.

In order to have correct call order loader checks if this
is last dependency in local group before adding it to BFS
queue.
