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.

so the file modification time can be accessed and reported.
