[imps] Updating tokenizer tests for the self-closing flag

[Henri Sivonen]

The tokenizer specification has changed to add a new flag: the self- 
closing flag. We need to change the test case format and the test  
cases accordingly.

The obvious change is to add a boolean at the end of the start tag  
array (true when the self-closing flag is set).

The less obvious questions are:

Do we want to make the boolean present only when it's true for  
backwards compatibility with test cases that don't involve the self- 
closing flag? I'd say yes.

Do we want to have the self-closing flag on end tags? I'd say no,  
because we are testing attributes either, and implementations should  
be allowed to optimize this data away.
