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.
