util/inteltool: Shrink buffer size
512 bytes is much too big for this buffer, which only needs to hold a
path that will have a length of at most 20. The large buffer size also
triggers a -Wformat-truncation warning with GCC since it is later
printed into the smaller temp_string array, so shrink it down to
something reasonable.
