Some filesystems nowadays use 64-bit types for timestamps. So, update grub_dirhook_info struct to use an grub_int64_t type to store mtime. This also updates the grub_unixtime2datetime() function to receive a 64-bit timestamp argument and do 64-bit-safe divisions. All the remaining conversion from 32-bit to 64-bit should be safe, as 32-bit to 64-bit attributions will be implicitly casted. The most critical part in the 32-bit to 64-bit conversion is in the function grub_unixtime2datetime() where it needs to deal with the 64-bit type. So, for that, the grub_divmod64() helper has been used. These changes enables the GRUB to support dates beyond y2038.
