Fix file path and line number errors when using `+`, `*` and `()`

[ydah]

This PR fix file path and line number errors when using +, * or ().

I discovered this when using the above new grammar in Lrama. Refs: https://github.com/ruby/lrama/pull/460/commits/df39a6f36535ac65e08a0a49eb84d6b944622e22 Refs: https://github.com/ruby/lrama/blob/df39a6f36535ac65e08a0a49eb84d6b944622e22/lib/lrama/parser.rb#L1270-L1282

As it stands, the second argument to module_eval is the absolute path to racc/grammarfileparser.rb and the line number. Perhaps specifying @filename and@scanner.lineno + 1 is correct?

Thanks for the PR. I think it's better to add test cases for this pattern. In this case, it's difficult to get line number and file name from actions, so I suggest to add test case in TestRaccCommand with assert_compile, assert_debugfile and assert_output_unchanged to check the output file difference. What do you think about it?

@yui-knk Thank you for your reviewing! I add test case for TestRaccCommand. How about this?
