[PATCH] vsprintf: drop printf hexstr fuzzer

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

This fuzzer was an early proof of concept as can be seen by the
useless initialized variable and its name is misleading:
It only tests the hexstr feature.

Unlike other tests, it also spams stdout. Let's just drop it for now and
perhaps bring it back in future in a more complete form.
