inteltool: cpu.c: Use conversion specifier `u` for unsigned integers

Cppcheck [1], a static code analysis tool, warns about the
following.

    $ cppcheck --version
    Cppcheck 1.59
    $ cppcheck --enable=all .
    […]
    Checking cpu.c...
    [cpu.c:951]: (warning) %d in format string (no. 1) requires a signed integer given in the argument list.
    [cpu.c:962]: (warning) %d in format string (no. 1) requires a signed integer given in the argument list.
    […]

And indeed, `core` is an unsigned integer and `man 3 printf` tells
the following about conversion specifiers.

       d, i   The int argument is converted to signed decimal notation. […]

       o, u, x, X
              The unsigned int argument is converted to unsigned octal (o), unsigned decimal (u), or  unsigned  hexadecimal  (x  and  X)
              notation.

So use `u` and Cppcheck does not complain anymore.
