register_module_notifier() does have "dummy" version but what
would I pass to it. It makes more mess than it cleans to declare
also a "dummy" version of trace_kprobe_module_nb.

The callback itself has too tight module subsystem bindings so
that they could be simply flagged with IS_DEFINED() (or correct
if I'm mistaken, this the conclusion I've ended up with).
