[Crash-utility] [PATCH 04/11] sadump, bug: time stamp values displayed are same

The bug happens, for example, in the following: printf("%s%s\n", (efi_time_t_to_tm(buf), efi_time_t_to_tm(buf))); where efi_time_t_to_tm() returns a pointer to buf, the address of the buffer passed to in the first argument. Obviously, the second call overwrites the result of the first call. It's dull to prepare a buffer for each function call, so I avoid this simply by calling printf() for each efi_time_to_tm() call: printf("%s", efi_time_t_to_tm(buf)); printf("%s\n", efi_time_t_to_tm(buf)); When the second call overwrites the result of the first call, printf() has already finished displaying it. Also I change efi_time_t_to_tm() so that it uses local buffer. It's safe if following the above use.
