Fixes #3987: Move r29953 to v1.7 branch (fix debugger type symbol lookup for mca_topo_base_module_t)

---svn-pre-commit-ignore-below---

r29953 [[BR]]
Fixes #3958: use the right type name (mca_topo_base_module_t) in the
debugger code (not mca_topo_base_module_2_1_0_t).

I checked: we do a similar thing for coll in the communicator struct
(i.e., leave the version number off the module struct).  I confess to
not remembering ''why'' we leave the version number off, but it seems
to be consistent this way...
