FAT filesystem supports timestamps until the year 2099
even though the theoretical max is 2107.
But, the struct timespec overflows in the year 2038 on
32 bit systems.
Use inode_timespec throughout the file system code so
that the timestamps can switch to y2038 safe
struct timespec64 when CONFIG_FS_USES_64BIT_TIME is
turned on.
Use a larger data type for seconds in fat_time_fat2unix().
This extends timestamps beyond the year 2038.
