Bug #9321: rb_mod_const_missing does not generate a c-return event

----------------------------------------
We have had an issue reported for ruby-prof where execution times were attributed incorrectly in the call graph.

It turned out that the problem is caused by a missing c-return event for Module#const_missing.

ruby-prof simulates the ruby call stack by subscribing to line, call, c-call, return and c-return events.

Obviously, the missing return throws ruby-prof off the track.
