(_dl_map_object_deps): Change return type and remove last parameter. Move code

to add map to global scope from here to dl-open.c.

-        since this structure was allocated very early (before the libc
-        is loaded) the memory it uses is allocated by the malloc()-stub
-        in the ld.so.  When we come here these functions are not used
-        anymore.  Instead the malloc() implementation of the libc is
-        used.  But this means the block from the main map cannot be used
-        in an realloc() call.  Therefore we allocate a completely new
