parse.y: brace after literal arg

* parse.y (symbol, dsym, parser_set_number_literal, parser_yylex):
  set state to END too not only ENDARG and after a literal, so
  that a left brace after it should be a primary block bound to
  the literal, which causes syntax error.
  [ruby-core:81037] [Bug #13547]
