[PATCH 3/3] KVM: selftests: Delete the unused guest_snprintf()

[Gokul K <gokul02k@gmail.com>]

guest_snprintf() is a varargs wrapper around guest_vsnprintf() that nothing
calls. Its declaration in test_util.h and its definition in
lib/guest_sprintf.c are the only two mentions anywhere under
tools/testing/selftests.

The rest of the family is alive: guest_vsnprintf() does the work and
ucall_common.c calls it, so this deletes the wrapper and nothing else.

No functional change intended.
