util/inteltool: Remove duplicated error message, switch to snprintf

Passing a string containing output from strerror() to perror() causes
double error message display. It is also causing segfaults when the
error message is longer than temp_string capacity.

To fix the problems, sterror() call has been removed so the error
message is printed only once. This could be enough to avoid segfaults,
but it is a good practice to limit output size with snprintf().
