Remove hack for ripper.y generation

Before Rearchitect Ripper (89cfc15), parser and ripper used different
semantic value data type for same symbols.
"ext/ripper/tools/preproc.rb" replaced these types when it generated
ripper.y. Starting the line with other than `%token` suppressed
the type replacement.
However, after Rearchitect Ripper, both parser and ripper use
same semantic value data type. Therefore these comments are not needed
anymore.
