[PATCH 03/10] common: misc: remove now unused errno_str

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

With all errno_str() instanced removed in a previous commit, we can drop
the now unused definition. New code should use

  printf("message: %m\n");

instead of

  printf("message: %s\n", errno_str());

or just use strerror(...) directly.
