tests: add fprintf() mock with redirection to io_mock

Browse Source 
We've seen somewhat obscure test failures where the real fprintf()
function was passed a fake file returned by the fopen() mock.

Although the code that caused the specific failure was cros-specific,
adding an fprintf() mock should help avoid future debugging.
