stubdom/vtpm: include stdio.h for declaration of printf

The function read_vtpmblk uses printf(3), but stdio.h is not included
in this file. This results in a warning from gcc-7:

vtpmblk.c: In function 'read_vtpmblk':
vtpmblk.c:322:7: warning: implicit declaration of function 'printf' [-Wimplicit-function-declaration]
       printf("Expected: ");
vtpmblk.c:322:7: warning: incompatible implicit declaration of built-in function 'printf'
vtpmblk.c:322:7: note: include '<stdio.h>' or provide a declaration of 'printf'
