Handle a trailing `:' in a user-supplied C++ namespace better.

* data/c++.m4 (b4_namespace_close): Don't let it be printed
among the closing braces here.  This fix might make the
generated code easier to debug, but otherwise it should be
insignificant because a trailing `:' is a C++ error already.
