dwarf_loader: Use zalloc() to allocate dwarf_cu 

We were allocating it with malloc and then trying to initialize it with
dwarf_cu__init(), which may fail and leave the dwarf_cu instance not
completely initialized which would lead to problems when calling
dwarf_cu__delete(), use zalloc to make sure all is zeroed.
