[PATCH 5/8] sandbox: stdio: fix ctrlc link error when CONFIG_CONSOLE_NONE=y

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

While sandbox defines arch_ctrlc() unconditionally, ctrlc() is not
defined when CONFIG_CONSOLE_NONE=y for all architectures, so we need the
inline stub on sandbox too to avoid a link error.
