kunit: tool: use `with open()` in unit test

The use of manual open() and .close() calls seems to be an attempt to
keep the contents in scope.
But Python doesn't restrict variables like that, so we can introduce new
variables inside of a `with` and use them outside.

Do so to make the code more Pythonic.
