When a class has prepended a module, the superclass is reported as itself.

module M; end
class C
  prepend M
end

C.superclass
# => C (in JRuby 9.0.0.0)
# => Object (in MRI 2.2.3)

I had a look here: https://github.com/jruby/jruby/blob/master/core/src/main/java/org/jruby/RubyClass.java#L1119

It looks as though we are walking up the inheritance chain and returning the first non-module we find.

Specify superclass in respect to prepend

This is mainly for jruby/jruby#3276, but also seemed somewhat
unspecified for CRuby - or at least based on my searching through
rubyspec.
