Add MODULE_VERSION to TCP loadable congestion control modules.

Browse Source 
Without versioning information, using preexisting loader /
linker code is not easily possible when another module may
have dependencies on pre-loaded modules, and also doesn't
allow the automatic loading of dependent modules.

No functional change of the actual modules.
