tests: fix build errors on OpenBSD
The cmocka.h header contains the following comment:
"These headers or their equivalents should be included prior to
including this header file.
#include <stdarg.h>
#include <stddef.h>
#include <setjmp.h>
This allows test applications to use custom definitions of C standard
library functions and types".
Include <stdarg.h> where necessary to fix several build errors on
OpenBSD 6.3.
