[RFC v2 01/12] Revert "kunit: move string-stream.h to lib/kunit"

[Daniel Latypov <dlatypov@xxxxxxxxxx>]

This reverts commit 109fb06fdc6f6788df7dfbc235f7636a38e28fd4.

string-stream will be used by kunit mocking code to print messages about
mock expectations.
It makes the code signifcantly simpler if string-stream objects can be
part of structs declared in mocking headers.
