vm_insnhelper.c: revive r44455 for bound module method

* vm_insnhelper.c (vm_search_super_method): when super called in a
  bound UnboundMethod generated from a module, no superclass is
  found since the current defined class is the module, then call
  method_missing in that case.  [ruby-core:59619] [Bug #9377]
