[Crash-utility] [PATCH] crash/s390x: Fix CPU timer and clock comparator output for bt -a

Hello Dave, The output of CPU timer and clock comparator has always been incorrect because: - We added S390X_WORD_SIZE (8) instead of 4 to get the second word - We did not left shift the clock comparator by 8 So fix this by getting the complete 64 bit values and by shifting the clock comparator correctly.
