nilfs2: use time64_t internally
The superblock and segment timestamps are used only internally in nilfs2 and can be read out using sysfs. Since we are using the old 'get_seconds()' interface and store the data as timestamps, the behavior differs slightly between 64-bit and 32-bit kernels, the latter will show incorrect timestamps after 2038 in sysfs, and presumably fail completely in 2106 as comparisons go wrong. This changes nilfs2 to use time64_t with ktime_get_real_seconds() to handle timestamps, making the behavior consistent and correct on both 32-bit and 64-bit machines. The on-disk format already uses 64-bit timestamps, so nothing changes there.
