Clean up lambda output from exyacc.rb
The `lambda_body` grammar rule has a `"}"`, which is throwing off the `exyacc.rb` regular expressions. This changes the regular expression to account for `"}"` as well, which makes the output of `ruby sample/exyacc.rb < parse.y` change by the following diff: ```diff 632,634d631 < ", &@3); < $$ = $2; < } ``` Which makes it closer to a valid EBNF.
