* struct.c (rb_struct_members): Refactoring. As Struct#members had

  returned an array of String, the old code was needed to convert
  Symbols to Strings.  But it is almost unnecessary because the
  method now returns an array of Symbols.  A patch by Masaki
  Matsushita <glass.saga at gmail dot com>  [Feature ruby#6218]
  [ruby-dev:45451]
