While playing around with a way to skip the seccomp get_metadata test, I
noticed that this header uses printf() without defining it, leading to,
../kselftest.h: In function ‘ksft_print_header’:
../kselftest.h:61:3: warning: implicit declaration of function ‘printf’
[-Wimplicit-function-declaration]
printf("TAP version 13\n");
^~~~~~
../kselftest.h:61:3: warning: incompatible implicit declaration of built-in
function ‘printf’
../kselftest.h:61:3: note: include ‘<stdio.h>’ or provide a declaration of
‘printf’
if user code doesn't also use printf.
