dynamic_debug: remove unused EXPORT_SYMBOLs

The only caller of ddebug_{add,remove}_module outside dynamic_debug.c is
kernel/module.c, which is obviously not itself modular (though it would
be an interesting exercise to make that happen...).  I also fail to see
how these interfaces can be used by modules, in-tree or not.
