This deletes some old code that apparently has been broken and somewhat unused for many years.
The 'derived_implementor?' method for modules relies on the debug output from Ruby in order to tell of a class implements a method, but the regex it used didn't work properly with any modern Ruby version until 2.5.x. This caused a random sleep to get inserted into certain payload staging operations, which actively breaks staging in certain scenarios (I'm not trying to address that here).
This also removes some ancient module feature detection code, which also is entirely unused today.
