jffs2: use 64-bit intermediate timestamps
The VFS now uses timespec64 timestamps consistently, but jffs2 still converts them to 32-bit numbers on the storage medium. As the helper functions for the conversion (get_seconds() and timespec_to_timespec64()) are now deprecated, let's change them over to the more modern replacements. This keeps the traditional interpretation of those values, where the on-disk 32-bit numbers are taken to be negative numbers, i.e. dates before 1970, on 32-bit machines, but future numbers past 2038 on 64-bit machines.
