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.
